Indeed. Trying to figure out how to fly helicopters was difficult enough, especially with mouse and keyboard, but then the game even required you to hit moving targets with unguided missiles. That had me cursing for a few hours. I especially remember the mission where you get promoted to squadleader and have to lead your squad to a town 30 or so kilometers away. Because the road was a deathtrap of russion troops with RPGs and the terrain impassable for most vehicles I couldn't use the APC like suggested and had to walk (!) to the objective, always watching for an ambush. Took me some attempts and many hours of my life. In retrospect I can hardly believe I completed that game. Then again, the experience was better than any anti-war movie.

I admit I was a fanatic concerning that game, but it made everything right. Well, it was not easy, but it was not meant to be. And with some training the choppers were great. Or the sniper rifle. If you took your time, you could hit the driver in the car 500 meters away from you. tanks were slow, but well, that's what tanks are :)
hmm, I think I should play it again...
