Sad thing is that I picked this game up yesterday thinking it can't be that bad but the above review sums it up nicely. My 5850 has a hard time with the bugs and glitches in this game as it is right now. The campaign is extremely short. Bad driving sections used to try and flesh out the game and make it feel bigger and longer than it is. Waste of 60 dollars.
This big thing is suppose to be the graphics and the super mega textures but they aren't that impressive after Crysis in 2007 being much more beautiful and Metro2033 is alot nicer to look at and is much more atmospheric.
Carmack said his biggest mistake was trying to develop for consoles and PC instead of making PC first priority. Well it shows in every aspect of the game so far.
Maybe if modders are able to work with this in the future something good will come of it but as it is now, save your money, buy BF3 or Skyrim and get much more enjoyment from them.
