I think it was all of the blasted reading and small font sizes in Morrowind. I probably sunk like 80 hours into that game and was just treading water. Oblivion, with the voice acting and more focused main plot, was much better imo. Sunk probably 300 hours into that game and the Shiver Isles and I did pretty much everthing that was possible. That was one amazing game....
KOTOR series is always great but you really have to play the first one to get the story right. You'll be kinda lost in KOTOR 2 if you haven't beaten the first game. I've replayed each of those games twice, something I rarely do. I played them each like nonstop for a week--I couldn't put em down or bring myself to play another game.
I think Gothic 3 is supposed to be fairly Oblivion-like but I've heard mixed reviews, especially about the weird control scheme. Maybe some one has an opinion on that?
RIght now I'm playing Darkstar One (it's no Freelancer but it's okay) and working through HL2 Episode 1. I need a new RPG, too. Offline, too. I've tried a lot of mmorpgs and I can't really get into them. Played WoW for a year but I got bored outta my skull after a while. Too repetitive.
