Planescape Torment is a great game, but what C&C does it have? Its a genuine question. I know that if you have high intellect you can have more memories, but other than that?
Upset Deionarra and get cursed, reveal the anarchist zombie and keep his secret or snitch, form Adahn through lies, join Dustmen/chaosmen/anarchists/sensates/godsmen, go through dead nations or warrens of thought, uncover silent kings secret and maybe become him, get mazed or killed by Lady of pain, free the siege tower, learn about and forgive Morte, learn of old company you adventured with, free, leave or destroy Vhailor, use the bronze sphere, complete and use Nihl Xanders dream machine, etc.
