I'm in a similar boat. I tried the cold turkey thing, deleting games etc. Cloud makes it harder now see e.g. WoW. Once I thought I solved my game addiction with the clever idea of leaving my Diablo 2 CD at work, thinking it would stop me from playing all night. That night I spent until midnight searching for NoCD cracks (successfully) and then played anyway until it was time to get up.
Nowadays I just figure if there weren't video games, I would be drinking or doing hard drugs with much worse effects on my health. I'm also able to moderate better, going through dry spells when I find something else to do for a while, and now and then playing nights (not too late) for a month or two at a time.
