I've played it. It's just a subpar military shooter.
compared to what?
I dare you to find me a "par" military shooter
and how long did you play it before arriving at this conclusion?
have you played it under the latest patch? it's been patched to shit in order to satisfy many of the original complaints that came on launch day.
<-- take a gander under Portal 2 there...
count every individual addon available for Arma 2, if possible.
there's at least 150k different things.
world objects (some of these packs contain thousands of items alone), weapons, uniforms, cars, planes, tanks, boats, interfaces, pre-made scripts and event triggers, sound effects, textures, graphics enhancements, custom missions, custom scenario maps, entirely new/original islands (some small, some even larger than the base island), gameplay mods, total conversion mods, etc.
