I’ve been interested in checking out some “DIY” boardgames, ones that you could just print the pieces/sheets/cards/tokens/etc and play.
I’m mostly interested in boardgames that can be played with 4+ people and require little setup or rules introduction, as I’m pretty much being the “gateway drug” for the group (everyone I’ve shown Blokus so far has loved the game).
I’m ok with knowing about heavy games (stuff that takes an afternoon to finish) to keep an eye on for future reference
The term you’re looking for is print and play. There’s a very large print and play community out there. Websites dedicated to sharing games. The board game industry is pretty open source as game mechanisms are not copyrightable. Only art and rules can be copyrighted.
