And I'm lovin' it. I'll sometime get slightly more indepth then that.
I'd like to now and all but you know... Oblivion.

Edit: So far, so very very awesome. It's leaps and bounds better then Morrowind, I can be certain of that much.
Thusfar my only critisisms lie in the NPC's schedules, they're supposed to have them but I still see too many NPC's standing about during the day doing squat.

Still, when it does seem to be in effect it's a marvel. People going in and out of stores, conversations between NPC's which, though sometimes partially non-sensical - are still interesting to listen in on.
Guards releaving other guards of their duty for a bit.

Yesterday, my little brother was playing. He was running following a path and eventually he came across a Khajit lady. She didnt really have anything to say, but the fact she was on the middle of nowhere and on the move intrigued us, so we followed her awhile.

We came across a wolf and leapt to her aid, but she did fine killing it with her bare hands. We came across another wolf, and with what seemed like a swift kick to the gut, killed it.
Lastly, there was a bandit on the road, ready and waiting to kill us and loot our bodies. But before we even withdrew our sword she leapt at the bandit with a palm strike and killed him in a single blow, which left us gobsmacked.

We followed her into a town, and into the towns castle. We followed her a little further til we hit a room that was locked.
Why was she in the middle of nowhere?
I don't know.
But to follow her as she went about her buisness and killed those things were awesome.

I'll give a summary of Oblivion later, though I haven't even scratched the surface - I've spent a whole lot of time just mucking about, so I cant make comments in regard to the main quest and story.
But everything else I've tampered with has been GREAT.
