for those on the fence about goy v. regular, id say go reg. I bought both and in hindsight would have saved the difference and put it towards another game.
Not saying theres no value to the content but I dont see myself getting enough value out of the extra for the difference in cost. (3d was a big letdown even with good av gear)
Besides, the truly hardcore are tracking down the 3d covers. Just depends on you want but if its just to play and the reg is cheaper, id go reg.
