One of those games that take a while to heat up, but become utterly incredible when you get immersed into it
The gameplay morphs to your preferences. If you know what you're doing, you can build a class that will really fit your playstyle. The first time around, you will probably make a crappy character, but if you read a guide this may be changed. There are probably hundreds, or maybe even thousands of character combinations possible with all the different races and classes, and birth signs. It's no longer about having to pick warrior, theif, mage, or archer. you can be hybrid (like spellswords for example)
The combat itself is quite satisfying. There is nothing more fun than using a claymore and slashing the face off a taunting daedra. The only complain is that in the rare instances where you have a teammate with you, they die way too easily.
Sound: The sound is probably what I would score lowest. It isn't that the sound was bad, but it doesn't seem quite as impressive when compared with the other factors. Yes, it does get slightly repetitive at times, and the game doesn't have any real main theme.
Graphics: Just gorgeous. Yes, they cause some bad framerates sometimes and some annoying loading bars, but the beauty of the graphics makes you wonder how the 360 can even process it.
Story: As stated before, I'm not finished with the main story, but having played around sixty hours of the game, I'm quite immersed, and I can say that it is quite a good story. It actually reminds me a bit of the Doom storyline sometimes (you'll see the oblivion gates, and you'll play the role of the doom marine).
It's a game that you will want a lot of time to play. If you play the first twenty minutes, and walk away, you may feel unimpressed. It requires time to warm up.
