I know I'll love it since I'm about 75% of the way through the campaign.
I just fear the multiplayer.
Also, X-Com looks a bit... outdated. By a couple of decades. <_<
So does Mario Brothers.
X-Com 2 was made before the industry started to focus on money/ graphics over gameplay, which is why it is good.
Do you think that if COD4's MP different that Halo 3 it means that halo has better MP?
Yeah, Halo 3 does have much better MP services overall IMO, but that's not to say that COD4 MP isn't great.
