One of the most immersive single player experiences I have ever experienced.
Simply put, this is a stellar game. It's easily the best Elder Scrolls game ever. A game like this only comes around once every few years. It is simply a must own game if you have an Xbox 360 or a PC. My only gripes would be incredibly minor. In fact they are so minor that they aren't really worth mentioning. The only reason I didn't give this game a perfect score is because I don't believe a perfect anything on this Earth could exist.
My advice to anyone new to this game, though, is don't use the origin where you are not granted magic regeneration. I played that character my first time through and it was so hard that I almost gave up on the game. You will constantly be in search of money to trade for more magic potions or ingredients for magic potions if you have the birth sign that I am thinking of.
A+++ Bethesda Softworks, let's see what Fallout will bring :D
