If you like killing many monsters, killing and killing and killing, just like in diablo and diablo 2; or if you usually play RPGs with only one character for more experience, then it is not a game for your taste. What makes torment a great game is the interactions between your group members,  quests (that many of them don't even involve killing), and wonderful reflection of the planescape universe.  If action is more important for you than non-killing quest experience, if you easily get bored of long text dialogues (some of them don't have anything to do with the storyline, but very helpfull to understand the planescape universe if you had no experience with it before), then buy ice wind dale or diablo2 expansion.  Ice Wind dale involves linear story line, much less interaction with npc s, more monsters and more experience.
