Not a bad game. It just has two large problems in my opinion. Firstly, you don't control the growth of your tribe. The game does and it adds new people whether you feel ready for them or not.
Secondly, whenever a castaway "levels up", the game switches to that castaway regardless of what you are in the middle of. I found when my tribe was full, someone was leveling up constantly. By the time I got control back, the castaway I had been working with was gone somewhere else. Became very frustrating, again, in my opinion
