Cod4 for the campaign and mw2 for the multiplayer although both games are among my favourites of the cod series plus cod4 had loads of cool glitches like the bounces, out of maps locations and some may disagree but the infections was fun for a private match.

I'd say cod4, for mike Myers
Liked mw2 a lot tho

I prefer MW2 because to be honest, it holds a special place in my heart as corny as that sounds. It's true!

When the game was in its prime, it introduced me to different communities within the game. GBs and trickshotting of course! Going a bit deeper, the trickshotting was an awesome ride at first. Made a bunch of friends, got into clans which meant I always had a team to play with. Of course after maturing, naturally, I began to realize that the whole trickshotting community was toxic and just lobby after lobby was just over the top ignorance.

During that trickshotting and playing I gravitated towards graphic design. I quickly got into it and challenged myself to get better. Eventually I acquired enough knowledge and skill to where I was comfortable with my level of experience.

I plan to go to college for digital graphic/advertising arts.

So I prefer MW2.

Mw2, i liked CoD 4 but there was just something great about Mw2. Made some awesome friends because of it and would love to have it back on XB1 as either a remastered version or just BC
