I've enjoyed me some games, and played straight through a few here and there. But I can't say I've ever been addicted. I suppose if the experience of those games were designed to last longer, I may well have been. But I've never felt that kind of compulsion or investment in any online oriented games. They just all seem to vapid and empty. The whole "grind for 50 hours to get one little thing" of MMOs, or the fact that MOBAs are designed to play the same fight over and over and over and over again with not a lot of gain from it always turned me off. The idea of talking to trout-talking 12 year olds the whole time doesn't really stack the pot much in my eyes either. So that completely negates any interest in online shooters like Halo or CoD

I've always been curious what that kind of addiction would be like. But people always get addicted to games I'm not interested in. Its like the games I consider good are non-addictive for some reason. Not sure where that threshold lies. I'd be curious to read a study of it, or watch a documentary on it though :3
