IMO, the most fun I had in CoD was MW2. I was in high school and I had a lot of my close friends playing that game.
It was most fun because at times we were competitive and wanted to win, but we were also able to fool around with Marathon x Lightweight x Commando and who can forget the Models? Quick Scoping (don't hate, it was fun messing around), games on Rust and even the glitches were fun (you know you tried them at one point).
Also notice how I excluded Call of Duty 3. I like to pretend that game never existed. --- You down with O.P.P? People that answered correctly: 37
I had the most fun in WaW, played S&D exclusively. The basic 3-5-7 killstreak made S&D tactical. Ever since MW2 introduced the modern killstreaks, care packages have ruined S&D. --- http://i55.tinypic.com/2a9ntxe.jpg
While BO2 may be my favorite CoD game right now for various reasons, I had the most fun playing Call of Duty: Modern Warfare 2 too. It is the CoD game that got me into the series. While I never owned World at War (until now on PC), I played zombies with friends and I loved WaW zombies back then. Right now, the regular zombie maps are kind of boring, which is why I got World at War for PC. Custom zombies! --- Xbox 360 Gamertag: TDPNeji Steam name: NejiHyuga900
