So, at this point I've been playing Oblivion for about.. 40 hours. The game runs surprisingly good on my computer (High-settings), so I haven't got any complaints about that.
The game itself is much cleaner than any other Elder Scrolls game. I mean, who haven't been pissed off at Morrowind's journal? I know I've been.
The system runs perfectly, it's easy to get what you want from the menu tabs, and the fact that it's been moved to the TAB-button instead of the rmb is just great.
The fights in the game is a masterpiece. Everything is fast, without being confusing. It's easy to take on multiple enemies without being fudged up, or dead, afterwards.

But, a couple of complaints. The third-person view. Yes, I know. "Oblivion is meant to be played in First-person". But why even use a third-person view in the first place?! It's almost like Bethseda deliberatly screwed everything about human physique in the third-person view, just to make the gamers go "WOW" about the first-person view. Oh, and it's not only the human physique they have screwed, they even went at the horses. Poor animals. They're lucky they aren't able to play the game, since it mocks their entire race.
And the AI of companions and monsters?! WTF. Why the heck do Imperial Watch guards question each other about what they're doing at that particular place?! And why do they find walls so damn fun?! Except when you use your bow, 'cus then they find the line of fire the greatest place to be. Sigh....
And enemy AI isn't very clever either. Example:
I'm competing in the arena. I summon a skeleton to fight for me, and run behind a pillar, and start shooting at my enemy. He just stands there, attacking my skeleton while my arrows sticks out of his ass, back and head. Not very clever at all.

Other than the above statemenst the game is great. I just wanted to get it off my chest.

Peace.
