As Roach says it has nothing to do with age. Playing with others, making teams playing vs teams is what keeps me playing. I'd say the addiction is like watching/playing soccer matches, it's the same thing it's just not healthy like actual sports. I don't want to get back to single player anymore. That's boring and a waste of time. I've been always playing nothing but Blizzard games. I got attarcted by some custom crap like making custom maps, modeling. It consumes your entire time, I'll never ever become a modeler or any of that mapmaker that wastes years on a map that no1 plays coz there is Dota, even if I do smth just for 1 map I do and is currently in frozen process. A war3 solo/2v2 game is 20 mins, a SCBW/SC2 may be 30 mins. This is one of the BIG reasons I prefer melee to Dota or any other custom crap, the endless WoW or other single player games... Wouldn't you spend 2 hours of your day? Sure you may be wayy busy but if you get up early do what you have to do for 2 hours you can do a lot of entertaining games. Now do you see why I talk so much about melee? Coz it's the best even in terms of time, awesome games and 2 hrs = at least 3-4 GGs. I've already thought of what is best if I become busy and it matches with what I like the most.
