I’ve seen a few games that use LEGO as playing pieces, but this one might be the simplest and easiest to learn. Should be a good introduction to role playing for young kids and non-gamers.
In a World Where Bricks Rule… is a set of icosahedron-based skirmish rules for brick minifigures. It’s bare-bones, rules-lite, and (hopefully) somewhat new-gamer-friendly. This version (0.5) is a quick intro to the derivative, yet fast and fun, game system. Also, J.R.’s artwork is great in it!
You can get large and pocket-size PDFs of the rules here: In a World Where Bricks Rule…
Thanks for the mention, Anton! More folks are able to check out the rules now. The spotlight is much appreciated!
