So I recently bought the game Rocket League
and it's really hitting all the points in being a really amazing competitive game and eSport. To sum it up, it's basically football(soccer) with cars. That might sound simple enough but there's a lot more to it.
You have a few tricks you can do with your car like jumping, boosting and kicking(?) and with those skills you'll have to manuever your car and succesfully score or defend against the other team. A standard match is 3v3 and each match is just 5 mins, which creates fast and intense matches where you instantly find yourself in the action.
