Giant in the Playground’s roller is tamper-resistant; any edit to the roll-code after posting, and the post gets a big red angry message and it messes up the roll.
But the real solution, of course, is trusting your players. If you cannot trust your players, you don’t have a game, and no amount of anti-cheat device will fix that. You need to fix ...
The website Invisible Castle had this exact functionality, and with this exact purpose in mind. It saved the rolls with tags for character, campaign, etc. You could look up the entire roll history of a player.
However, Invisible Castle seems to have gone down, possibly permanently. The site has apparently changed hands and now tries to install suspicious ...
You're looking for Obsidian Portal.
Obsidian Portal is specifically designed to allow tabletop RPG groups to build their own internal wikis. The privacy options are apparently undergoing an upgrade right now, but if nothing else you can set the whole campaign as private, so that nothing is viewable to anyone except people you invite.
Hero Lab is the premier character generation software for Pathfinder (and a variety of other game systems). It's commercial and costs more than PCGen but it's also way more usable. You have to buy content packs, and it can get expensive to get them all, but they have the content available for all new Paizo books (and some third party) available at or very ...
PCGen is a completely free Open Source character generator and maintenance program, and can do what you are looking for. And even a bit more.
I personally use it for GMing a group of six very different characters, print out their character sheets, and I also can create monsters with unique abilities, having additional levels in various classes etc.
Roll20 is another option you should consider.
It runs in the browser, allows you to upload images to be used as tokens/maps from your PC and provides a number of other features that sound suited to what you want.
Battlegrounds hosts a table comparing popular virtual tabletop software. One of the comparison lines is whether it's "Suitable for offline use".
Based on the comparison, the best bet is MapTool since it explicitly notes that it supports dual map windows so that the player map can be moved onto an external monitor. The other entries indicate support for in-...
I've been able to find a couple. I had better luck searching for "form fillable" pdf "ad&d 2e" instead of "modifiable", since that's the term that Adobe and therefore most PDF creators use. Here are a couple good ones:
A character sheet based on the TSR original for a an AD&D setting called 10th Age can be used for other AD&D 2e settings. The ...
Spellbook - D&D 3.5 is a free app that allows you to lookup spell descriptions and create custom lists of your spells. It includes all spells from 3.5 SRD. Very useful.
d20 SRD 3.5 Spell List is a free app (in Beta however) it lists your spells per day and allows you to organise them into ones known.
Spellforge is an excel based system for ...
Roll20 is a subscription service that uses HTML5 features to work on all modern browsers. It may be what you are looking for.
The features you are asking for are available on the free plan. However, support for tablets requires a paid subscription.
Update: Roll20 now has its own tablet apps for iOS and Android
Both Medieval Demographics Made Easy and The Domesday Book - Medieval Demographics Made Easy were found using this Google search. Both are from the same author (S. John Ross) but both have sources you could delve into.
The www.medieval-life.net site offers some information as to what life was like which should tell you what people did which will inform ...
One tool that might suit your needs is Freemind.
It's meant to be used for any kind of idea jotting (I've used it to take campaign notes).
And being tree-based it's probably good to give it a shot.
It's free and open source.
It looks something like this:
(Tree branches are collapsable. The third question is collapsed in the image above)
From your question, I imagine you need this to a play-by-forum game, and wouldn't be online at the same time than the player.
If you CAN be online at the same time than the player, just go to Rolz, create a room a you're done. If you can't, just go to Rolz anyway, create a room and you're done.
Rolz save all the logs from rolls, so you can make your ...
Labyrinth is exactly what you want. You have the ability to populate multiple maps with characters, places & objects, link them together and write a bunch of notes for every one of them.
Also there are a time tracking tool and plugins for cryptography (yes, riddles) and relationship calculations.
The simulationist computer game Dwarf Fortress (http://www.bay12games.com/dwarves/) has a 'legends' mode that is, in essence, a world history generator and will also provide an (evolving) map.
It is noted for its depth in culture/world details, so it might be a good fit; and our gaming group has used it for world map/location/NPC generation.
Hexographer is a tool for creating hex maps by painting. It offers a number of icon sets and is capable of working in color.
You can try the free version to decide if it is right for you - for many, the free version is all that is necessary.
While it can do map creation (and even map fill-in), it is not just a generator. If your vision can be ...
There are many character creators for fantasy games in computer gaming.
The PC versions of many RPGs have extensive character creators. The Dragon Age series, and the World of Warcraft game have extensive customization options.
There is also the custom miniature creator HeroForge - https://www.heroforge.com/ which is designed to let you visualize your own ...
Google hangouts. Invite yourself twice, mute one instance.
When I've presented at conferences, remotely, I've driven two instances of google hangouts in exactly this way. So long as you've got one of the instances' audio completely cut out (I recommend the screenshare), and enough bandwidth to push both, you're just fine.
You have to use multiple google ...
I have used Donjon myself, but not in a while. I just checked it, and the site is up. I find the site usable, but lacking.
Other Creator I have not used:
Third Edition (3.5) Dungeons and Dragons Character Generator
Yours truly has created a variety of form fillable character sheets:
"Dumb" sheet (which only has fillable forms): Here
"V2" sheet (has some calculation capability): Here
"V2.5" sheet (extended to a third page, more calculations): Here
Note that 2.5 is somewhat obtuse to use; in V2.5, the modified attributes on the first page feed from modifiers given on ...
I would recommend using Roll20.
This will allow the GM to edit map and tokens from a tablet browser (requiring Chrome at the moment), while sharing to the web browsers on players' PCs. It will optionally integrate with Hangouts, but does the job pretty well on its own.
Roll20 lets you create a map from images and tiles, or by whiteboard-style drawing on ...
The one I personaly use is this one: Kobold Fight Club
Works well for my needs, can be used to generate a random encounter for your party, only downside I found is you can't seem to input levels if your party is of different levels.
It's not exactly a wiki, but we've used Google Docs to similar effect.
I'm not 100% sure how we pulled it off, but I think we had a wiki earlier and actually migrated its data into Google docs. That particular group was all programmers, so someone could have done something fancy or someone could have had a copy/paste-fest while watching TV.
From our POV ...
As excellent as S. John Ross Medieval Demographics is the list seemed incomplete. So I traced back to the original source, Paris Tax Roll of 1292. The main issue is that S John Ross worked with a secondary source that didn't use the full list. So I went through the original data and compiled my own version. The full explanation can be read here on the Bat in ...
There is a 3rd party app, cbloader, that can be used to extend and create new content for the offline version of the character builder (which you would need to find a copy of).
You should be able to implement a custom class in that, though you will need to know how to edit XML files.
Since this question was originally asked, more options that might give a better solution have become available. Specifically, the Roll20 online virtual tabletop.
With Roll20 you can invite people by email address and they can play as their character while in-game. Some tools make it much easier even for new users, including irc style chat, voice chat and ...
No tool like this exists for Rogue Trader...
I spent about half an hour searching around on google, forums, and the official Rogue Trader site to see if there was anything approaching what you described and there is not. In fact the only tool of any kind I could find was for star system generation (and everything within)
However, you shouldn't be the one ...
Nearly all mapmaking software aimed at RPGs is exclusively for Windows, which makes it hard for GMs who are Mac owners to find anything to create maps, if they don't have the technical and artistic skills that mapmaking with a photo-editing suite requires.
The one RPG mapping tool I've used to good effect that is available on Mac is Hexographer. (It's Java, ...
