This is the ONLY game I've been playing lately. Only got 20 minutes to spare? Right there is 3-4 games, in and out. Extremely rewarding as you improve over time. Simple mechanics and fun unranked modes for 'casuals' yet extremely high skill ceiling for pros which is also why this game is a big contender for eSports going into 2016.
If still on the fence, snag it when it goes on sale. See you on the pitch
