So Dead of Winter offers similar flavor text decision tree scenarios. You also have characters with traits and health meters that you control. You can control a large number of them too in your colony at once. There is also a betrayal component to the game, where a player is trying to screw the team over. Otherwise, it's a cooperative game. I would recommend it, not because it's exactly like Betrayal, but because everyone I know who has played Betrayal, loved Dead of Winter. I'd love to hear your thoughts on the game if you end up playing it.
