Rocket league looks very interesting from a competitive point of view. We are planning on spawning a dedicated team with pro ambitions. If you are up for it let us know on the forums and introduce yourself.
Some people might actually remember the old mod carball in ut2004. At least i have played a decent amount of it. The completely restyled version on the unreal engine 3 is called rocket league and shows amazing competitive potential. store.steampowered.com/app/252950/?l=english
