The Elder Scrolls IV: Oblivion has the highest amount of depth and detail I have ever seen in a game.
The gameplay itself pits you against creatures and, if you feel like it, people although in this area they have chosen tough baddies and not many of them rather than lots of easy enemies to butcher. Having said that as you advance through a level scheme, you fight more bad guys depending on how highly levelled your hero is.
The graphics themselves are stunning, and can give some really great scenes. But the best thing is, if you see a mountain in the distance, you can actually carry on running until you get there. The skies and water look very realistic, although the graphics are perhaps let down by the way trees and grass can sometimes suddenly appear in jerky motion.
The sound is good, each race and gender seems to have 1 voice which, while sometimes feeling like a letdown, also gives a unique sound to each race. The background music is good, although occasionally it can get in the way if you're trying to listen to a character whisper - Nothing that the audio menu can't change, though. The background music features an array of tunes while you're journeying which fit in very nicely to each theme.
Lastly, there is the depth which Oblivion has. I have never encountered so much detail put into a game before. Firstly, there are thousands of books which you can pick up and read. These can tell you lots of valuable information about treasures or storylines, or even helping to increase your skills. Besides that, there is the amount of rumours that change as you play the game. You can ask any random person for rumours, which can lead you to a new quest or treasure, perhaps even discussing a hero who helped rid a place of evil (That's you ;)). On top of all this, there are an endless amount of caves and lands to explore, a selection of guilds as well as an enthralling storyline, which I won't ruin for you. There are also many wepons, bows and arrows of different standards and qualities. And hell to learning magic spells - in this game you can make them. Yes, I said make them. There is even more depth in oblivion, giving this game an endless lifetime.
Overall, Oblivion features a great amount of depth with a good mixture of graphics, sound and gameplay. Although if there was one improvement they could make, make more mindless, easy-to-kill enemies, and make lots of them attack you at once!!
