It cannot be told what torment is, you have to live it yourself
It uses the same engine with baldur's gate but it
's WAY different. Tormant is the most original RPG of the last decade but not the best and most entertaining one but just original. This game is so well thought that you may think it's really non-linear. For example, you can die in this game anytime you wish YET use it for your own favor if you're smart. This made me remember Robin Hood, it's gameplay was nearly non-linear, very similar to torment's. Anyway I'm supporting these titles especially Planescape: Torment. It's NOT a RPG like any other. Not everyone likes it though, I personally can't finish it for there are too much dialogue and I'm easily bored.
