Okay, mefolks are the exact same. Keep saying I shouldn't be playing games for that long.
My suggestion is, for the time being, limit your gaming. Don't do it as often and only do it when your folks aren't there. After doing this for a week, my folks didn't have too much of a deal with it.
Keep busy with things your parents like. It may seem like a very childish thing to do, but see VMK as a reward for getting stuff done (subconciously, that's what your parents may do).
Get into a zen-like nature and treat VMK like a drug. If you are able to kick the addictionh, you'll play very casually (not obsessively) and your parents won't mind.
