I'm starting to develop my first sandbox campaign ever, I'll be using 5e to run it and I'll start the game in October, so I'm taking these two months to prep everything.
I'm using Hexographer as my go-to software, however I have several issues on how to develop my Hexcrawl world:
A Little about my Setting
I took two source materials to inspire my world: Nier and Fragile Dreams. Both are post apocalyptic worlds where magic exists, and enemies are mostly incorporeal beings or creatures that represent the "past" of mankind. I took Nier's magic usage, fantasy and varied settings (deserts, plains, coast, mountains) to think of the base world, and then Fragile Dreams for the dungeons (as I plan for my dungeons to be abandoned hotels, malls, hospitals, amusement parks, etc, that now are hosted by goblins, ghosts, drakes, etc).
The only races I'm gonna let my players run are Warforged, Dragonborn, Dwarf and Human.
The world has only a few inhabitants left and traveling is something only a very few brave (or foolish enough) do. My players are just villagers who are stronger than the rest, who will travel to unravel the mystery behind a sickness that makes people disappear, which s related to the past of their world.
Villages are few and far between, there are no big cities, people are mostly very friendly or very paranoid, and they live in structures similar to ours but with more of a "medieval" society build. There are still modern sewer systems, and some minor modern technologies such as basic medical care exist, but communications, traveling and such is "old school".
- I can't decide the size of the world. It's supposed to take my players from Heroic to Lower Epic Tier.
- Being a hostile world, I don't know how many encounters I should throw in per day.
- Since there are only about 5 to 6 human settlements that count as "hubs" in that world, the rest being only small housing areas with about 3-4 inhabitants, I don't know how to fill the rest of the hexes.
- Besides the dungeon, what else could interest my players and bring them enough action and roleplaying in such a desolate environment?
