To the surprise of absolutely no one, the arbitrary two-year timeskip seems to have been put in so they could make you buy some DLC explaining what happened during those two years. It comes out next month, whoopee.
Basically this game is more of the same, like the previous one? Where you did the same mission over and over again. But it's getting lots of hype, and the HD graphics, so i guess most kids these days will go OMG I MUST HAVE IT!! and then go to the internet a week later to cry about DANG THIS GAME SUX!
