I loved the mission when you were in the forest and had to high tail it out to get back to your troops.
I lost interest in it, though, when I was given command of the units....just took too much out of me...couldn't keep up, so I never finished it.
Nor have I finished ArmA, which I considered a good game.
I do have ArmA but it bored me after a while, it just didn't click.
As for the first one I kinda know what you mean. It was at its best at the beginning, when you're just a grunt and doing patrols on your own, being ordered about by sergeants and stuff. Later on when you were in charge it wasn't quite as cool.
The Red Hammer expansion has some crazy missions, Dmitri Lukin is like Rambo or something. I remember one mission where you have to break into a base, steal a fuel truck, drive the fuel truck to an airport, use it to refill the Hind there, and then fly the Hind out and blow away some M1 tanks. I think I was trying to do that mission for an entire week, it was crazy hard, and Op Flashpoint only allows one save...
