Ven3ance it's quite good, but not perfect. It's not trying to be arcade-like. Compared with the BF series, it's less polished with the user interface, but it's also more immersive. Can you buy it somewhere with a 30 day return policy like (perhaps) Best Buy? I'm not sure in what country you are living.
It's good, and its also a nice contrast (for me) to playing BF2142. I like both games for their own reasons. 2142 is much more of a finished game, imo. There are certain clunky aspects to ArmA, like how many animations need to finish before you get control of your soldier. For example, when you fire your RPG and want to arm your rifle, it can take a while.. You can't just throw the RPG down and arm the rifle quickly.
Perpetual debt is slavery.
