Never actually bought the game myself. Even though I had never played Day Z when I heard of it just looking at their "Game" and the fact that it looked like mediocrity compared to a mod was enough to turn me away. I ended up playing Day Z about a week ago finally and now I love it. So if you're interested, the winter sale is a good time to pick up Arma 2 for cheap.
