He also didn't mentioned the utter lack of cross-bows. I had so much fun with cross-bows in Morrowind... and here you have a useless bow. Stealth-hit gives x2 for bows? Erm... guys... it doesn't matter if I hit you with an arrow square in the head if you see me or not... you are fucking dead one way or the other.
I also liked Morrowind more. Oblivion is not bad, that's not the problem, it's just mediocre. At the beginning it's exciting and new but once you got around you've seen it quickly and then it becomes boring.
The main story line really is the worst I've seen in a long time. The side ( and especially guild quests ) are a lot better. Dark Brotherhood and Thieves Guild are the best side quests. All the others are very annoying.
You can play this game in a week since enemies ( no matter if common or bosses ) are affected by your level hence you can rush through at level 1 and beat the game. That's one of the jokes.
Another joke is fast traveling. Of course I used it all the time since it is so utterly boring to ride between cities just because some stupid quests requests you to fetch a dull item from one place and bring it to another. I want to play a game and have fun and not ride miles along boring and repeating scenery to do errands.
It's one of those games which has this bad property that whenever you even remotely think about playing it again it repels you by only thinking at the bad problems it has. And if a game repels you more than it attracts you then something is wrong.
Kudos for mentioning Thief-II. You should also mention once Deus-Ex ( NOT the IW crap ) as a god father of FPS+RPG mixture

( well, besides SS of course which inspired them )
