Yes I do, and YES its FREAKING AWESOME... Cant really compare it to COD4, but in a lot of ways I like it better. The maps are much larger making the game a lot more tactical. The issue I have with COD4 is its constant run and gun. Not saying its not fun by any means, its just difficult to utilize strategy on that game.
SOCOM, is just awesome, IMO It always was, I have been a SOCOM veteran since the first one came out. This one like all the others has their server issues but they will be ironed out very soon. I like using team based tactics to accomplish the goals rather than being a one man team.
