I had a real job finding it in the shops. I went to HMV, Game, WH Smiths, Virgin and they only had the PS2/Xbox version out and I was really confused.
So I walks into another Game store and just ask the dude if he knows anything of the PC version of flatout 2 and he was like "uh well if it ain't on the shelves then I doubt we have it, but I will check anyway". Sure enough he opens his big drawer and its bursting with Flatout 2 PC games. He was like, "Oh that is weird, why haven't these been put out."
Useless idiots

Next time your near a game shop, its probably worth asking.
