Planescape: Torment

An eternal war

The endless Blood War rages, a never-ending battle between the fiends of the planes. Amid this horrific conflict, a single hero with no memory of his past seeks to discover his true identity.

Of course, this being the planes, his companions on his quest are ... unusual. But if you can't trust a floating skull, an eccentric investor, and a succubus, who can you trust?

Practically no one.

Based on the best-selling computer game from Interplay.
