Yeah, I was in a rather melodramatic mood yesterday, when I wrote that. ;) I do maintain the "text vs graphics" statement though, but I probably should have worded it differently. Graphics are very often the better medium for things that _can_ be visualized. However, there are lots of things that can't (thoughts being one of them), and shunning away from text basically robs you of one powerful method of artistic expression. If you look at today's AAA titles, then you can't help noticing that this method of artistic expression has been lost to contemporary game design, and (imho) not for the better.
Think I agree with the main sentiment there. New games usually have a lot of focus on fancy grahpics and nice explosions and various other effects, while less focus (or none) is put into thoughts and such things that can be relayed via text. There must be action action action all the time, while the more subtle variations, that we see in books all the time, are lost to the medium now.
Coming back to the topic, that is the main strength of Planescape Torment. It's much more text based than other games, and it has an incredibly good story that is well-delivered via the text-focused gameplay. We therefore connect to the characters much more than in other games, certainly others I've played, and the brilliant story helps to drag us further into the game.
This kind of design probably won't work unless there is a rock solid story underneath it, but it's wonderful game and is heralded as perhaps the best RPG for good reason. It's actually possible to roleplay pretty good in it, which isn't the case for most, if not all, modern RPGs.
The game also differentiates itself from others in that it has some deeper meaning, that you are likely to ponder while playing the game and at its end. It's borderline philosophical. Simply an excellent game. It's not for everybody, perhaps particularly in today's gaming world with so much focus no action at all costs, but once you put in a few hours and start to get dragged in, you will reap the rewards.
