User Rating: 9.7 | The Elder Scrolls IV: Oblivion PC
I have been playing the Elder Scrolls games since Arena and I can tell you they just keep getting better. I don't even know where to begin. Almost everything about this game is perfect. It is visually astounding from the wilderness's to the cities, caves, and dungeons. The music and sound effects are top notch. As for combat, I couldn't have hoped for a better system. The sheer intelligence and aggressions shown by your enemies gives you a real since of being in the game not just controlling a character in a game. Every time a monster runs and jumps at me I can't help but think he would come through my monitor and stab me in the face if he could.
The story of this game and all the side quests and factions can really draw you in. You'll spend countless hours adventuring and not even realize it. The only complaint I have, as small as it is, is that everything levels up with you. I always enjoyed becoming an all powerful god able to crush any one with a simple thought, but alas in this game as you get stronger so do your enemies. With that in mind Bethesda couldn't have made a better sequel to an already great line of games.
