Yeah man this is what you do for maximum earning efficiency:

Set your quarter length to 12 minutes and game speed to 100 wherever that setting is. Start a quick game where you control neither team (controller should be in the middle and not say P1 or whatever) and I usually set a timer on my phone for about 55-56 minutes. You come back when the timer goes off and there is usually just a minute or left in the game. Then take control of one of the teams and finish the game and you get somewhere around 1100-1250 VC for an hour. Sometimes you get more and sometimes less; it doesn't matter if you win but I always make sure to. As long as you play at least one second of the game you get that VC. After you do it a couple times you can set the timer higher or whatever and play less of the game, but I have found 56 minutes always makes sure I don't miss the end of the game. I do this when watching TV, eating, or whatever TF you want to do. If you have any questions just ask man.
