Amazing - yet...dull...
I must say it is quite a piece of work, a game like this. It is nicely realistic (as infantry at least) but the problem there is a lot of long range shooting at a few blurry pixels and equally getting shot by something you can hardly see. This is all well and good but I can't help but think, 'Am I excited by this game? Am I on the edge of my seat wanting to play more? Is it intense?' and unfortunately the answers are not very positive.
I think GRAW is about as close to realistic I want to play that answers 'Yes' to the above as well - no doubt this upsets all the mature ARMA fans but oh well. OA is very good, it is just not much 'fun'.
