Simply put... the game of the year
Also don't let gamespots "best on Xbox 360" fool you, it most certainly is NOT. If you have a really top of the line PC this game will look a lot better the Xbox 360 version, have faster loading times, less stutter when entering new areas AND most importantly you get the hundreds if not thousands of FREE excellent mods of which the Xbox 360 does not have access too.
Gameplay: 9: The gameplay is great but like many reviewers say your not sure how the combat could be improved exactly but there is definate room for improvement in that area, because it just doesn't feel 'right'. Also AI could be better.
Graphics: 9 - Some of the best graphics you will see but the only reason it doesn't get a 10 is the ugly distant landscapes at stock game (without mods)
Sound: 9 - The sound quality is excellent in the game but the constant re-used voice actors can be somewhat annoying when you are speaking to different people and they sound the same. BUT! It has to be said there must be hundreds of characters or more that all have great voice acting (no just text, everyone has a voice) So the quality is excellent. Just could have done with a bit more variation in actors.
Value: 10 - Although there is room for improvement and little niggles in the game which would suggest it isn't worthy of a 10; chances are you will find what you are looking for from one of the many great mods around from the almost profesional like modders. Also some mods add new quests, equipment, gameplay, areas etc and this new FREE content isn't going to slow down soon, so chances are when your finished playing you will have some new things to download to add to the game.
Tilt: 10 - It's an amazing game with countless things to do and different styles of play for all. Also like I said "simply put... the game of the year" need I say more?
