Avalon is a social "hidden identity" board game for 6 to 10 players. Each game has 2 teams, the good guys and bad guys, but only the bad guys know who each other are. Through proposing a few players at a time to go on "quests" and then voting on whether or not to approve those quests, the good guys must try to figure out who the bad guys are before it is too late.
Wireframes and mockups are limited in how much they can convey the feel of software. This is why UX Pros prefer Interactive Prototypes.
