idk about MW2 but the original MW was better on PC. The PC version was updated more, and you could have more players playing in a server. The only thing the PC version didn't have was that restart rank shit.
Infinity Ward didn't include Dedicated Server Support in their PC version of MW2. Everyone was "very upset" by this. Everyone "boycotted" the game. Cancelled their pre-orders and then proceeded to buy the game TWO days after it came out, in protest.
Fortunately, we're talking about the internet here and the game was modded to include DS support and the very first multiplayer game with server settings played was a Low Grav Infinite Nade Spam match.
The game, however, is more or less a straight port from console to PC.
This is the reason I don't play CoD: <kickass scores.jgp>
It just feels too easy.
It varies on 360. Really time-of-day dependant.
3 pm to 7:30 pm on weekdays is "RAPE THE CHILLUNS!" time. This time is fun time.
8 pm to 12 am is "GET RAPED BY PEOPLE THAT ACTUALLY UNDERSTAND THE GAME MECHANICS AND SPEND TIME PLAYING" time. It's more of an educational experience than anything else.
