Ok, so I have only played the game on the 360 for around 2 hours, so I can't give you a full rating, but I would say from what I saw and the style of games I like, it would be around an 18 out of 20.
This game will blow the first morrowind out of the water. The gameplay is smooth. The screen loads are so smooth. (Remember morrowind on the xbox. Screen loads froze a lot. Not in this game)
The xbox 360 controller is weird at first, but once you get used to the hotkeyed buttons and what not, it is very nice. Visually, I expected more, but that isn't to say that it wasn't awesome. Very pretty scenery.
Character customization- You'll spend an hour customizing the look of your character and then be like, you know what, I'll just hit this random button until I find a look I like. They have customization for like every part of the face. Forehead, ears, nose, chin, jaw, mouth, ect... you get the point.
Battlesystem is similar to the first game.
The guards and everyone in the game seem to scale to your level. I was an hour in the game and killing guards or patrols. In that respect, it is nice also.
After killing and looting everyone in sight, I rested and awoke to a spirit hovering over me that asked me to join the "dark side" pretty much went into an explanation on how their order kill for fun and loot for fun and blah blah and asked to join. I said heck ya and he said to prove my allegience I had to go kill some random person. Not sure if this is the assassin guild or another, but it was pretty cool.
When you kill a person, you can pretty much loot anything he is carrying (weapons, shields) and loot his corpse(gold clothes, ect..) What else do you want to know?
