I agree that the game does require an investment of time to a degree although as a Sim Racer, I have grown to like that in my games.
I think give multiplayer a shot with some guys from this forum. You may see the other side to the game as the developers intended. It does offer something VERY special, just stick it out and you will be rewarded.
Regarding multiplayer, give it a few months, when all the randoms have got bored and moved onto OFP

R the Multiplayer will be great again as it was in Armed Assault.
Another reason I love ARMA is the community is a more "Mature" one compared to most games nowadays although that is why I like my Sim Racing as it is a more mature set of gamers and banter consists of more than "YOU SUCKOR$".
Give it a few more weeks too when it is FULLY released and we arrange some games from this forum, should be great fun and I imagine that the majority here would want to play the game as INTENDED.
