I'm going to be ordering it tonight on Amazon! I'm so excited. I'm a Prime member so it will get here on Friday and basically spend all night Friday & all day Saturday playing.
Got it yesterday and I love it! Wasn't expecting the game to run on the same engine as GTA 4 though, I was kind of expecting a graphics update, and a new engine but then again it is on the seventh generation consoles so....ya but I do enjoy it and the game world is HUGE
They're likely in the process of making a PC version seeing as they publicly noticed the want for it to not be only console based. I give a month or two until it's on Steam.
