This is what's great about AH, there's something to do if you're beginner or expert, if you're starting out you can always fly the goon, it's the easiest and most important part of the game and people will be greatful to you.
The ground vehicles are pretty easy too and are important for defending a field.
Most important thing is a decent 3d video card and joystick, it's not much fun without the right equipment.
