Despite some fixable flaws, this game is definately one of the best on the market.
The fighting system is very well done, some big improvements over morrowind. Shields are manually usable and you don't have to switch to magic-casting mode to cast spells. There is so much to do!! Because the game is so immersive, it has tons of replay value. The ability to create and use mods is a huge bonus. And for only $50 new? You might spend 600 hours and play through the game 3 times before you get sick of it. Worth every penny and then some.
There are some sound flaws, such as the voice volumes. You might walk 3 inches away from someone and they say something to you, but if you enter talking mode, their voices are much louder. Somewhat unrealistic, but I'm only nitpicking.
I am rather ticked off that Bethesda released this when it has such ridiculous glitches. I've had the game for just a couple days and it has crashed 6 times. Ridiculous. It happens when you enter a new area; it typically loads, then there is a black screen, then the game shuts off. Other than this, there are just small, unimportant, easy-to-ignore problems. PLEASE come out with a patch soon to fix this Bethesda!!
I don't play games much, so maybe I'm easily impressed, but graphically this game is better than any other PC game I've seen on the market--I'm comparing this to F.E.A.R., Battlefield 2, etc etc (all the "good graphic" games). Since this is like a first person shooter in many ways, it should appeal to FPS fans whether or not they like RPGs. This game is very easy to recommend.
