I've played my fair share of flight games, and I'd have to say either my config setup is poor, or again they really need to work on the implementation.
The first failure is that you "need" to switch controls to pilot the craft, that's a design issue. The other is I'd say the controls are very clunky feeling.
It's not as responsive, or as accurate as it could be using a KB. I'm probably setting myself up for disagreement here, but with as many people that
jump in and immediately crash - I'd say it needs a little bit more hand holding in terms of maintaining altitude and auto-leveling. Landings could make
a bit more sense than just dropping the chopper at low altitude.
I've even went to YouTube and tried watching some vids to get an idea, and folks there are stunt pilots compared to me. I went from ascending and
crashing back down, to staying aloft for a couple minutes till a random tank picks me out of the air. Haven't had much issue with other choppers or RPGs though.
Compared to older games from across the flight combat or FPS spectrum, I just think there's room for improvement.
