This poster from Inkwell Ideas is a large map of roleplaying games.
The RPG poster comes complete with a small set of monster stickers. The idea is to use to stickers to mark the games you’ve played and therefore your progress through the RPG dungeon. The games are divided by genre and so you pick an entrance from one edge of the map, each edge matching a genre or RPG, and then move to the first room by following a question about the type of RPGs you like.
Inkwell have packed the overview of tabletop roleplaying games with lots of in-jokes and homages.
