Only game I've felt addicted to in well over a decade, probably closer to two, would be World of Warcraft. While I was married, I played a lot of the game due to my wife never being home. Wasn't really addicted since I would stop the second she got home or if I found something better to do, but it was fun and I had a ton of time on my hand. But then came the divorce, and my life became WoW. I know it was mainly me not wanting to face the real world, so I dove head first into my character's world instead.
But then I found myself playing more than even that. I was not sleeping. I was calling into work to play. I wasn't satified with just one character anymore. Ended up with seven, all maxed level and well played each day. Had dozens of more characters across several servers also that I played with friends. I would sleep maybe two hours, wake, do about fifty daily quests, run a few instances with friends, and then raid, and then raid again on another character, and then another if time permited. If not, there was always some PvP.
Eventualy I found myself lost. Friends quit playing or fell behind, in-game material became irrelevant cause I already had it all, anything new quickly became old. And my eyes opened for the first time in a long time.
My friends, my co-workers, even my ex-wife were all still out there in the real world, just waiting for me. I greeted them all with open arms (except my ex) and quickly found there was indead life after divorce. It was time to move on and find myself again. The real me, not just some character.
