Planescape: Torment is a top-down RPG made by Black Isle Studios (closed in 2003) and released in 1999. This game focuses more on the story telling (the 'role playing' part of RPG) than fighting. It has some really nice and funny dialogs delivered in both voice and text. You can avoid many combat situation by talking your way out of it. Which is pretty nice. The game received very high review scores but didn't sell too well. I was hoping for a sequel after I played through it the first time on my old junky computer way back when.
