I bought Arma 2 about 8 months ago because I played it a mates place, and I still think it's a bloody good game. Then about 4 weeks ago that same mate told me about this mod, told me to check out some vids on Youtube and I was sold. Within the first 5 mins of the vid I knew I wanted this. Unfortunately I didn't have a credit card, but my mate bought me Operation Arrowhead. I have had so much fun since. Like Griff said, this game actually makes you feel shit. Contact with other players is often very tense. Do we fire? Are they going to fire? But you know they are going through the same thing, and I really enjoy the psychology behind it all. I have been gaming for probably 16+ years, this is the first game I have gotten adrenaline rush from. TL;DR: FOR THE LOVE OF ALL THINGS AWESOME YES
