Was hugely disappointed in the 360 version beta, sure it would look better on PC but not really ready for PC gaming at this time. I'm not even sure this is prettier than MW2, it might be actually worse in some ways (kinda reminds me of that $10 first person shooter they sometimes push on xbox live, can't remember the name right now)
Also I felt no sense of tactical strategy or anything, though with all the noobs running around on a beta that might be somewhat expected.. But really I found nothing here that hasn't been done a thousand times before, which sucks cuz this was the game I was most looking forward to this year.
