They just love to boost their own egos. I swear COD4 may not have had "more guns" or "more perks", but at least it has dedicated following and thousands upon thousands of dedicated servers. Hell I went and played some last night and I admit it's more fun then it is when I played MW2 online. The fact that I was able to open a server browser, play three maps without intermission, and then leave without the worry if I'm the host or not was wonderful. Sure MW2 may LOOK prettier, but really all I see is COD4 graphics with HDR and maybe an up on the texture resolution.
