Yesterday I played Bloodborne the Card Game and loved it! The theme, however, is a little dark for my family (getting killed several times, collecting "blood echoes" which are blood colored chips, and an overall lack of bright colors). What games have similar mechanics and game length, but with a "lighter" theme?
"Bloodborne the Card Game" is a cooperative/competitive card game where you fight a series of monsters and collect victory points that can be lost when you die if you haven't cashed them. You start with five cards and gain only a few more cards before it's over that upgrade your character. It lasts 30-45 minutes, and is for 3-6 players.
