A Huge, Beautiful, and Addictive Role Playing Game.
Oblivion is a beautiful RPG. The environments are colorful and full of life, the NPCs are done with an overall awesome art direction and the architecture is crafted in a realistic manner.
Oblivion is an addictive RPG. I clocked over 100 hours on it. It'll probably take the average player around 30 hours to finish the main storyline and there are plenty of side quests to do after you have finished that.
Oblivion is an awesome game that you should pick up if you are a 360, PS3. Even if you aren't into RPGs you'll want to try this one out.
