Best game I've ever played, especially compared with all the glossy s**t being released today.
I've seen a few reviews complaining about the graphics in the game, but I really don't see much to complain about. The graphics are fine for 2000 and perhaps the reason the interface seems tiny now is because of the high resolution. On the intended resolution (800x600) the interface is easy to navigate. The tutorial feature helps any new player learn the features quickly enough (the tutorial takes about ten minutes).
What helped me fall in love with the game was the gameplay. The main story is extremely engrossing and entertaining. The characters and npcs are colorful, each having a distinct personality. The vast amount of side quests is probably what made the game what it is. The side quests have an individuality of their own, revealing different parts of the world and allowing for greater equipment, skill, and companions. This might seem like a common feature (in games like Neverwinter Nights), but it's difficult to describe with words; you really have to experience it for yourself.
There are a few quirks in the game. I've played it through a few times and I always get this annoying bug that disables the character scripts. This makes it annoying in battles with many opponents as you have to control each character individually. There's also a bug with the spoken text (too complicated to explain).
All-in-all this is a fantastic game and should be at least given a chance (past the dungeon). While the multiplayer isn't so active anymore there are many mods (as well as an expansion) that can add a lot of replay value to the game.
