When I first tried A10C and DSC World (flyign the SU) I did not like it. I couldn't figure a damn thing out and after 2 hours of trying to figure out the controls I just gave up.
I let it sit for a month and then took the time to read about the systems, controls and what they all did. I watched some videos and started running the tutorials.
I realize now that I was to impatient when first stating the game up. I wanted to get into the air, and not take the time to learn.
After fixing this personal problem, I absolutely love this game!
As someone said, its not "hard". Its just complex. Very complex in fact that it could be very intimidating and frustrating. It is also very rewarding when things go right and all time you've spent allows you to rain destruction down on those pixelated tanks!
Moral of the story: Buy it!
Cheers,
