I don't understand why Planescape: Torment gets so much love. I tried it out because of the hype, and found it has an interesting world, but the story itself was pretty vanilla, and the engine was just another form of isometric D&D game. I was bored and gave up halfway though.
Sure, the story might have improved towards the end, but a good story should have you throughout, and not make you drudge through the early stages.
Isn't it obvious? Torment wasn't a game, it was an interactive novel in disguise. The most interesting stuff in the game doesn't happen in the top half of the screen, it happens in the long lines of narrative and dialog at the bottom.
