I think what works for me is "less is more" - as in only purchase or play 1 or 2 games at a time and only if you want to play them. After graduating and getting a full time job, I found that I lacked the energy to play games after work, although at work I would read about them still.
Having income made me purchase all these games I read up about but never had the time to play them. The end result made me have a gigantic backlog across all systems - this stressed me out a lot because I jumped to about 5 different games within a few hours and couldn't decide on one, so barely any progress would be made. So I got rid of some of them (mainly the xbox and tons of ps3 games) and narrowed it down to only a few games.
