# How does D&D 5e compare to AD&D 2e?

I played 1st and 2nd edition AD&D a lot back in the day. But when 3rd edition came out, I dropped out of the hobby. Partly I just couldn't be bothered to re-learn the rules. The conversion systems, previews and material for 3rd edition I was seeing in Dragon and Dungeon magazines made it look like a very major change.

I recently picked up the new 5th edition starter set on a whim. Obviously the starter set rules are very stripped down in comparison to the full rules, but nevertheless, I was amazed by how comfortable and familiar the system felt. The only thing that felt like a truly radical change was the way things like thief skills and the like were now handled with a d20 instead of a percentage system.

There's plenty of information online (and here) comparing editions of the game in an incremental manner. But I'd be interested in a breakdown of how 2nd and 5th edition compare directly, specifically looking at whether there are broad areas of similarity.

I played many years of 2e (and BECMI, 1e. 3e. 3.5e, PF, and OSR stuff) and have read the 5e PHB, Basic set, and Hoard of the Dragon Queen and played some short games, so I think I can give some good points of comparison. I'm excluding the Skills & Powers stuff in late 2e from this discussion, that was less like 2e than many other versions of D&D itself.

There are definitely similarities between 2e and 5e — mostly conceptual and "feel" similarities. The individual mechanics are different — pretty much entirely, except for the basic "rolling to hit involves a d20! AC is involved! And there's saving throws of some sort!" kind of things all the editions share; none of the numbers or tables or rolls are identical.

It's almost as if 5e was a do-over of 3e, with the benefit of many hard lessons learned from the 3e → 3.5e → 4e experience, mostly about limiting power inflation but avoiding the risks of trying to mitigate that through making everyone the same. I think it's fair to say that in retrospect 3.5e is a min-maxer's wet dream and dissolves into non-fun at moderately high levels from rocket tag and op disparity; 4e tried to fix that but was in the end unsuccessful because it made everyone vanilla and identical in the process — reminiscent of in WoW, how "At level 1, you kill boars... Now that you're level 70, you can go farm level 70 demon boars!" (See also: Some Thoughts On 2e and 3e's Legacy.)

## Power Limiting Through Mechanics

5e uses bounded accuracy and advantage to obtain the same power differential limiting that 2e did with just "fewer bonuses." Everyone's addicted to bonuses now, so you can't not have them, but they take a different tack to try and get a power level more like 2e's. In 2e, for those who aren't grognards, there was a lot less difference in power with level and/or Hit Die. You just couldn't stack many bonuses on top because they weren't available. A level 5 person wasn't infinitely more than level 1 or less than level 10, the curve was less steep. 3.5e easily degenerated into people with +0 bonuses and +30 bonuses and "rocket tag." The 5e mechanics are trying to solve that problem with a different mechanical approach, but with a result that feels like halfway between 2e and 3e power level wise.

You'll hear people with yesteryear's goggles on complain about "all those unbalanced kits in 2e!" If you actually go back and read the kits after playing 3.x+, you'll wonder what the big deal is. Most kits would at most get you a free weapon or nonweapon proficiency. One of the most "unbalanced," the Berserker, lets you get a +1 to hit/+3 to damage by going berserk (raging). An 18 STR gets you all of a +1 to hit/+2 to damage in 2e. Back in the day, combining that into +2/+5 was a HUGE bonus — now, we call that "a first level character's standard attack and damage bonus, if they are poorly optimized."

The 5e class configurability options are like a cross between 2e kits and Paizo's class archetypes — more like the archetypes in how much of the character they swap out, but more like kits in terms of "choose just one, permanently."

## Power Limiting Through Randomness

Rolling stats reduced power by reducing optimization. That was stock in 1e/2e and is back in as the default gen method in 5e (things went all point buy in the interim).

The concept of creating and buying "to spec" magic items introduced in 3e has also been removed. It was a lot harder to come up with broken combinations when you couldn't just "sell that thing I just found for 50,000 gp and demand the perfect 50,000 gp item for my build in return." In 3.5e you had a "wealth tax" in that you were expected to have a whole suite of +(level/3) enhancements to everything.

So it feels like 2e, more than it feels like 3e/4e, because you can't custom craft every aspect but have to rely on the campaign and luck to a degree.

## Other 2e-Like Stuff

The one thing that really struck me was the art similarity between the 2e PHB and the 5e PHB on the interior art. Especially the full-page color plate pics but also the character treatments really made me think "2e!" while I was reading it. Each edition has had very specific art direction and 5e's looks a lot more like 2e's than any other version.

The skill mechanic has been dialed back from "lots of skills" to more like the 2e NWP mechanic where really you just have a couple, while retaining the 3e style mechanics.

Spells and stuff are just shorter, too. This makes it feel like 2e just because it was a midpoint between the more terse BECMI and the more verbose 3e. (e.g. Knock spell — BECMI: 122 words, 3.5e: 206 words, 5e Basic: 132 words)

And finally — attitude. Mike Mearls and the WotC team have been trying to get everyone to take responsibility for their own game and rules again. The GM guidance in 5e is conceptually similar to the strain in BECMI and 2e per How has D&D's guidance to DMs on when to extrapolate from written rules and when to improvise changed over time? A lot of the confusion over his talk about "living rules" is a straight up conceptual shift - he talks about "living rules," and then people only familiar with 3.5e and/or 4e turn it into "Living Rules(tm)" and debate its exact definition. He's just saying "Goddamnit people loosen up!" In 2e we house-ruled a lot; any 3.5e/4e question about house ruling here is usually answered with a Careful Admonition To Not Do So Lest Ye Upset The Holy Game Balance. They're basically trying to bring some of that old approach back — I guess we'll see if they can change their fanbase as easily as in the past or if that's a Pandora's Box that it's hard to close.

## A Bunch Of Non-2e Stuff In 5e

Of course 5e also has a bunch of stuff from 3e — feats, similar core mechanic (THAC0 replaced with the pure d20+bonus vs difficulty), similar way of stating rules, multiclassing, no level limits.

It also has a couple things from 4e — mainly weird proud nails from the "UberBalance" (like the "you have to use your action to make your animal companion attack!" bit). And healing surges transformed into Hit Dice recovery made confusing by sticking the "Hit Dice" term on it. Monsters being not like characters is 4e-ish but also 1e/2e-ish.

It has very little from 1e that wasn't also in 2e; the focus on the "three pillars" of combat/exploration/interaction for example, is familiar from 1e but also in 2e. 1e and 2e were mainly different in that 2e cleaned up the super arcane parts of the rules (to-hit tables) but also cut the super arcane parts of the fluff (most of the DMG, including random harlot tables).

And 5e has some net new stuff not from any previous editions, like the indie-game inspiration and bonds and stuff.

• Thanks for this comprehensive answer. It's interesting that it sounds like the Starter Set (which is all I've looked at) has a much more 2e feel than the full 5e rules. It bypasses things like dual-classing and chosen feats, making it look more like the old fashioned fixed gain of powers as levels advanced. It also incorporates many things that were common house rules like fast healing and no level limits. Sep 8, 2014 at 9:14
• excellent answer. I'm one of those who wears "yesteryear goggles" however I'm also way ahead of the current WOTC team and the "Goddamnit people loosen up!" philosophy. I prefer the old ways (AD&D) because quite simply... a great campaign is based on 2 things: a DM's intelligence and creativity. Period. Smart and creative DM's would realize "Hey, I've paid lots of \$ for these books and modules and in order to enjoy years of play, I'm going to bend whatever rules I want within limits, so my players have a GREAT time and we keep on playing." So I combined D&D, Basic, 2e, and AD&D lol. Aug 26, 2021 at 5:19

# Is the Starter Set Stripped Down?

The starter set is not really stripped down rules of play. It contains the same content as PHB and PBR chapters 7, 8, 9, and 10 - which are the actual rules of play. All it stripped was character generation (chapters 2-6) and many spells (Ch 12) and setting fluff (appendices). The included pregen characters ARE fully legal 5E PHB builds. Note that much of the rules complexity of 5E is in character special abilities. This is much like AD&D, especially without Non-Weapon Proficiencies.

# What's the Evolutionary path of 5E?

5E draws many concepts from 3.X and some from 4.X, but also goes back to Original D&D and AD&D for others. As with 3.X and 4.X, it's a redesign from first principles. It is really, the direct child of 3.X and AD&D 1e

• It keeps 3.X/4.X ascending AC.
• It keeps the fighter being the only one to have lots of attacks of AD&D, but strips most of these from the Barbarian, Paladin and Ranger.
• The list of classes is essentially the "greatest hits" of AD&D through 3.5.
• The races are subdivided into the subraces mentioned in AD&D 1E's Unearthed Arcana.
• It keeps the 3.X and 4.X roll high on 1d20.
• It adds an entirely new roll modifications mechanic (Advantage/Disadvantage) which replaces most of the modifier lists. (Now, modifiers are generally ±2 or ±5, in the few cases they are used at all...).
• Spellcasters gain competence comparable to 4th ed ones - 1st level casters are still glass cannons, but no longer 1 shot artillery. Cantrips being At Will is taken directly from 4th ed, and likewise, cantrips growing at the breakpoints where fighters gain additional attacks.
• Multiclassing is taken largely from the 3E model, but only Proficiency Bonus grows with character level. Spell slots grow with "Caster Level" (which can be from multiple classes)
• Spell Casting and Memorization have changed. The default now works like the 3E sorcerer.
• General Presumption of broad competence - everybody can try most things. They may not succeed, but they can try, and good attributes are highly useful in that regard.
• Array Build - while it appeared in 3.E, it's really taken from 4.0. It's also optional, except for organized play, but the balancing assumes it.
• Higher Hit Die types - Taken from 4E.
• Flat Points Per HD - Taken from a variety of sources (including non-D&D games)... and it is generally better than standard HD rolls, but not by much.
• A climbing proficiency bonus originates in Star Wars Saga Edition... and from there, coopted into 4E and again, but reduced in scale, in 5E.
• The 4E healing surges chand name, but still exist.

# The Design Goals.

It is built around 3 explicit goals, and one implicit:

1. Streamline play.
2. Keep the iconic classes recognizable.
3. Rebalance the system.
4. (implied) Regain audience share.

# So, What's Like AD&D 2E?

Realistically, not that much. Plenty, tho.

• Most rolls are made on 1d20.
• Most classes have access to non-combat skills as well as Magic or combat.
• All the 2E core classes exist, except basic wizard: Fighter, Ranger, Paladin, Cleric, Druid, Specialist Wizard, Rogue, Monk. All wizards now make a transition to specialist (arcane tradition) at 2nd level.
• Support for both gridded and Theater of the Mind play
• Plenty of suggestions for character hooks.
• Emphasis on skill driven play. AD&D 2E Non-Weapon Proficiencies were officially optional, but were an assumed default despite the label. (Note: unlike AD&D, there's no unskilled penalty, only a bonus for being skilled.) 5E DMG allows avoiding the use of skills as an option.
• Most of your favorite magic items from AD&D 2E will have made the leap.
• Explicit permission for the DM to tinker.

Now, note that AD&D 2E in the wild had a few common options in use in most groups:

• 4d6 keep best 3 for attributes (Variant I in 1e, Variant V in 2e) - it's back as the default in 5e.
• Options for non-magical healers - it's back, and open to everyone - but it eats a feat.
• Hmm, having played 5e for a bit, I don't find that the skills are optional(in your last section). What is it that you meant by that? Did you mean that feats are optional? Oct 13, 2019 at 13:17
• @KorvinStarmast edited for accuracy. While technically correct, it was poorly worded; there is an option in the DMG (p. 263) for skill-less play in 5E, looking very much like the approach in Castles and Crusades. Nov 1, 2019 at 18:53
• Aah, light goes on thanks. :) Nov 1, 2019 at 18:59
