Each level has many, many areas for you to cause destruction, and more objects are prone to damage than Carma 2. I don't like how you have to finish a level to qualify for the next, making it, short of cheat codes, a long trek to find out what the next level looks like. This is exactly like Carma 2 in this respect. There is a free driving option, which takes away time limits and lets you just bomb around any levels that you have currently completed. What I really noticed right away was the speed of the Eagle, which seemed to possess more power than it did in Carma 2 at the beginning of the game, thus making the play feel faster.
Controls are identical for the keyboard.
I have never used a wheel with this series so I cannot comment. With my system, I run it at 1024 and haven't had a problem. I was a little worried buying the game because I had heard that there was framerate slowdown, but so far that hasn't happen. Real solid, no bugs noticed. Carma 1 still has the crown when it comes to the music.
