A great card game with lots of interaction as you trade with other players to collect sets of matching cards. You are presented with choices to make every turn (no mindless card play here), but you'll only have a few options so the game won't ever get bogged down.
Players need to understand that trading is the heart of the game so don't be shy about it. There will even be times when you want to give away something for nothing.
Creates a great balance between dice-rolling and role-playing so it should appeal to a variety of RPG player types. The rules are fairly easy to learn and never slow the game down. While made for a survival horror setting, the Unisystem rules are also easily carried into other genre's or settings.
