My brief review should be published in a few days. Reading the Gamespot review, I could not think of a case where I have disagreed more with an opinion of a game.
Overall, I give it a passing mark. Perhaps I am unique in the world, but I have yet to suffer a single crash of any kind, through several hours in the campaigns and even more hours of multiplayer over the last couple of weeks. Performance has been better than I hoped, even with SMAA enabled. The things that do drag down IF in my opinion, are the same old Arma bugs we've been seeing for many, many years now. Personally, I doubt the possibility that a licensee of the Arma engine can miraculously remake the franchise from the ground up, solving all it's problems. But working with what the engine does offer, the package offers great content, a decently playable single player end, and the vast potential for more from 3rd party missions.
For my own interests, it's going to live or die on the multiplayer community growth.
