Arma 2 with ACE 2 is fun, but its not real like DCS. I'm waiting for DCS to get into the FPS field. Maybe in a few years, after they come out with their Fighter, because a REAL Arma type world is going to take a POWERFUL computer to run it. The Arma 2 world has a ton of problems, and low realism. We need a REAL FPS, with REAL armor and REAL weapons. In the end, Arma 2, even with ACE 2, is still just a glorified game.
