What makes Chloe so special is that the game plays with all the usual chlichés while at the same time not falling for them. Chloe is not blond, not dumb, not a helpless victim of some players schemes / seduction / corruption. Instead she is smart and stupid, naive and clever, self-centred and altruistic, fun and funny. In other words: real. The story might be repetitive at times, ridiculous or not too logical. Yet, the contradictory and constantly exploring girl succeeds with something that hardly any other game can provide: she feels real and interesting, and I enjoy every new episode, every new angle, every new development, no matter how much grinding I had to provide.
Yes, the game also has some weaker moments, but, all in all, there is no other game I know that preserves the same freshness and originality. The spin-off (Hanna) shows clearly how easily the Chloe-game could have fallen into the cliché trap. But: it didn't. And that makes the game very special.
