indeed, I love fantasy RPG's as well. What I don't get is people who worship Fable. I mean, sure, it was a decent game, but it was short, and it didn't really live up to the expectations that people had for it. There were side quests enough, and lots of things to do, but they made the game so that you were usually trying to do a story quest and at the rate the game progresses you just don't have enough time to properly explore and take in the whole game. The side quests were decent, and the customizability of the character was good as well (hair, tatoos, name etc), but Peter Molyneaux (spelling?) has set a standard for his games that people expect.
BTW I hated Pazaak from the start. I generally ignore it. The thing I liked about the kotor side-quests though was that if you did enough of them, the actually advanced the story in some way. Fr example, if you pester Canderous enough, and you are on tatooine at that point, he will meet one of his mandalorian buddies and they will fight, Canderous of course pwns the crap out of the dude, but thats besides the point
Also, in kotor 2, if you pursue the side quests enough, you can make most of your non jedi party members jedi, aside from Mandalore aka Canderous of course, he doesn't need to be a jedi to pwn. All of the secrets are good too, especially in RPGs since there are so many places to hide them. If you look closely, you can find many relics of the main character from kotor (who's name wont be revealed incase of spoiling it) within kotor 2, and you get this nostalgia, een when you see characters like carth, who in the first is horribly annoying, and you appreciate the fac that they brought him back. Everything aside, a good RPG IS hard to find, perhaps why people love them so much. If they are good, they are REALLY good. If not, they suck.
