Planescape: Torment was just a giant string of mindf--ck throughout. Spoilers ahead, so be warned. Although let's be honest here, if you haven't played the game by now you probably never will, so whatever you might as well keep reading.
Anyway, yeah. Finding out about your previous incarnations is absolutely mind bending. Especially the one fairly recent 'you' that created an elaborate series of traps to try and lure you, aka himself, into it and then kill you, aka himself, in a grandiose attempt at multi-generational suicide. Not to mention the whole thing with the army of shadows being sent out to kill you, not in an attempt to actually 'kill kill' you, but actually in an attempt to keep the main character from ever progressing to the point where he's capable of questioning and struggling against his own unnatural nature. And that's not even the kicker, the kicker is that those shadows are being sent by the main characters own 'mortality' which after having been taken from the protagonist who knows how long ago eventually became its own independent being, struggling itself to stay alive by keeping it's originator; the player, immortal.
So your mortality is trying to kill the player in order to keep the player immortal so the mortality can remain immortal...

That's the sound of my head exploding. And I haven't even gotten into Ravel, the Blood Wars, Trias the Betrayer, the nature of those shadows, the Nameless Ones various exploits during his various 'lives', or the games ending among other things.
