I played through it on...
AMD 1.8ghz PC with 1/2 Gig of ram.
Radeon 9800XT.
Detail levels quite low, but it played well most of the time. It's a repetitive game that falls far short of the publishers claims, but the first time you do things it's really fun. For instance, one of the guilds, the assasins guild - well everybody joins that, and it has some really great missions in it, but when your done, it becomes your job to act as go between, go to one location, talk to night mother, go to brotherhood base, talk to freaky chick, earn 200, come back next week.
That's as interesting as it get's once you complete a guild quest set. I'd prefer that it picked a non-vital NPC at random, and had you put them to death. The most fun is when your offing the guests at the treasure hunt party, there should really have been more of that.
When you first play the main quest, you have to enter and close your first oblivion portal, now that's cool, but then it's reduced in coolness the 12 other times you have to close an oblivion portal, they're like mazes most of the time, before long they become an irritation.
There's just a million things I'd change about it - still a great game, still one of the best PC games in years, but damn, are games testers only interested in showstopper bugs these days or what! - it's like a gorgeous world filled with cool stuff, but the cool stuff is all made from rubber, like a dogs chew toy. I know I wasn't expecting the hourglasses to work or anything unreasonable like that - but really, how difficult would it be to have smashable glass items - it would actually help performance as it would get rid of physics entities, things like that would make the world more realistic.
