Wow, what a fantastic game. Bethesda knows what they're doing and Oblivion is a prime example of their mastery. This was the first title for the X360 as well as the first next gen title I purchased and as soon as heard Patrick Stewart's captivating voice I was hooked. This is one of the very few games that has actually moved me emotionally and has really took a hold of my life. It may sound weird but it's really that damn good.
Oblivion is the fourth installment in the Elder Scrolls series and is arguably the best out of all four. It's an action RPG that provides a magnificent open world to explore, kill, or just collect herbs if you wish. The game has a fantastic main quest that you can immediately complete if you'd like or you could do what 90% of players do and go off on your own to explore and do many of the fantastic side quests available.
You begin the game by crafting your own unique character by utilizing the incredibly detailed creator tool and then your sent through a dungeon which serves as an entertaining tutorial. As soon as you leave the dungeon/sewer you will find yourself feasting your eyes upon the incredible land of Tamriel. You are free to go about your business and get yourself involved in quests, guilds, alchemy, enchanting, horse riding, cave exploring, treasure hunting, arena fighting, or any of the other dozens of activities available to you.
I promise you that as soon as you set foot into Tamriel, you will be hooked. I have had this game since it released in 2005 and I still play it vigorously. Do yourself a favor and grab yourself a copy of Oblivion. You will not regret it!
