My wife keeps me in check. Not in that she's telling me when I can play, but that, I'm thinking about her before and while I play, and whether or not I'm being considerate.
@Rhynoplaz It's one of the reasons I hope to not spend 10+ hours a day on games as I do enjoy my time with my partner but it has turned into you watch things on the TV well I play some games that I've already been playing all day.
