So now that I've finished Torment (and thanks to everyone who answered my call for advice, BTW), it seems appropriate to come to some conclusion about the game.
First of all, the experience was well worth it. If there's anyone left around here who hasn't played Torment, and thinks he might want to try, I say go for it. The odds of your being disappointed are very low. In my opinion, Torment is the best of the Infinity Engine games, hands down.
Let me say a few words about what I liked most.
[spoiler:15cd6bb6db]The story is a cut above most game stories in several ways. The sheer amount of dialogue content in the game is surprising, and that content is well-written. There are two specific things I like most about the story. Number one: it's a tragedy. A tragedy! Off the top of my head, I can't think of a single game besides Torment that doesn't have some sort of happy ending. "Winning" in PST means your character is banished to an apparently eternal afterlife of horrible punishment - and he deserves it. There is no choice of doing things a certain way that leads to a happy outcome. Bending over backwards to be the ultimate goody-two-shoes doesn't help. That's a gutsy move for a commercial game...and it works. Number two (and this is inextricably linked to number one): your character is not "The Chosen One" destined to save the world from The Forces of Evil (TM). How refreshing is that? If you "lose" the game, the universe is not destroyed. No one recognizes you as the last hope for your tribe/civilization/planet.

That said, I agree with some of the criticisms of Torment.
[spoiler:15cd6bb6db]Replayability is an issue. I find I have no desire at all to play Torment again - not in the near future, at least. Sure, there are some different options for different kinds of characters, but due to the nature of the story all paths lead to the same conclusion, regardless of the kind of personality you decide to give The Nameless One. Also, Torment is a game that demands the player pay close attention to the large volume of dialogue. If you don't pay close attention, you'll miss things. I don't have the concentration to play the game that way again. It's like I just finished reading a novel, and now I'm supposed to read it again right away. It doesn't work.
And there's nothing else to draw me back, since, for example, the combat is bland at best. The "game" parts of Torment are generally pretty bland, in fact.[/spoiler:15cd6bb6db]
Buying a copy of Torment is inexpensive after all these years. It's well worth the price, especially with years and years of fan-made fixes and mods free for the downloading.
