I dont think this game is worth 15€, but i picked it up for about 4€ and I spend hours on top of hours playing this game. Especially the space stage is so fun. The game might feel like a combination from different sorts of games, but less develloped. (f.e. in the tribal stage where you have to produce troops etc, it feels like a low priced rts game.) But its the combination and the evolution of your own character that truly makes this game "fun". So I highly recommand this game for this price.
