Even though I enjoy it, sometimes I'm happy I can't see the hours put in a game. I wouldn't want to know how many hours of HoMM 3, ADOM or Final Fantasy 7 I've played in my past. Now there are only few games I've put 100+ hours into, mostly because of adult responsibilities and other boring things, just like you.
Dark Souls is a game to learn something. Maybe it's patience, maybe it's not. I think that I'm already quite patient, but now I'm learning to keep my head cool. I don't mean I'm getting angry at the games, but I'm prone of making bad decisions when I'm in stressful situations.
And I'm not enjoying myself too much yet. The largest pleasure so far is that I'm kind of doing OK :D
