I've just spent the last 20 minutes watching some HD footage of it, and it seems to be worth getting in my opinion..
I'll most likely wait for it to hit the bargain bin though as I can already tell it's going to go there.. It's not getting enough sales to stay at such a high price..
But Yeah, It seems pretty cool, sort of CoD style sort of shooting.. & the graphics aren't half-bad either. They beat Half Life 2's graphics hands down..
