"Given the shortage of hardcore PC-only games these days it's refreshing to see an independent developer such as Bohemia Interactive striving to achieve such a lofty goal - that of a fully immersive military simulator playable on a standard (albeit powerful) PC, not a supercomputer. One can well imagine the technical and gameplay compromises that would have had to been made if Arma II was a multi-platform title for both PC and consoles. As it is, the game struggles to run at a decent frame and uses pretty much every keyboard combination you can think of.
Ultimately, while Arma II isn't the most realistic tank or flight simulator, these elements are of secondary importance compared to the infantry warfare gameplay. What's more, I can't remember the last time a company released a proper tank or flight sim on the PC, let alone one that simulated combined-arms warfare.
Yes, Arma II still has a fair number of bugs, yes it runs like a one legged drunken horse from time to time but no game, civilian or military has come this close to simulating the terrifying, vulnerable world of the modern infantryman. Poor bloody infantry indeed."
