I'm enjoying reading these comments about people who say they'll always game! I remember chatting with my mother when I was much younger and saying I'll always watch nickelodeon. Why wouldn't I? It has such great programs like sabrina the teenage witch and kenan and kel!!
In my experience I play games less often when I'm working. Last few years I've either been in College or working. Whilst at College I can easily play some console games in my spare time or the evening, so i'm a casual gamer. I just can't do the obsessive PC games like play Dota for 10 hours a day.
Currently I'm unemployed since changing careers and I've plenty of time to play dota. I know for a fact that when I start my new 38hour week job where I'll have two days off a week. I'll be spending those days cleaning the house, going to the gym and working on my relationship with my partner. Gaming just won't be in there. I'll probably cut out playing dota completely via playing it less and less to the point where I just won't have the time to invest in playing. On the upshot I'll get back into console gaming and can enjoy a game like MW2 on singleplayer, only 6-8 hour game you say? It'll last me a good few months due to my lack of free time.
In short,
You'll game less when you start to settle down, i.e move out of the parents house, get a 'career', move in with the girlfriend which then leads onto having the wife and kids scenario- you just won't have the time to commit like you do at the moment.
Question is, why did I stop watching nickelodeon?
