Recently I re-started playing Rocket League. One of the main reasons I like it is the 6 - 7 minutes it takes for a match to run: you know how many you can play in an hour and plan in advance when to stop.
That being said, I have to confess last Saturday I spent an insane amount of time with my Xbox, whether it was for gaming or Netflix... still have to improve!
