Mice & Mystics is like D&D with no DM, and only combat, no role-playing. It's fun, but I can only take so much of it before it gets tedious. My son made up his own 3-tile chapter to play with his friends. They got through 2 before they quit to go wrestle in the living room. They seemed to be having fun while it lasted, though, and they're only 10, so their attention spans are limited.
Jab, I painted them from the character card art. No other reference is really needed, though of course you're welcome to look at mine if you find it helpful.
