It's interesting to read the responses to this thread. I find these definitions to be very nebulous and apply in very limited situations. I do tend to agree with Lethality's sentiment. The difference between Hardcore and Casual comes down to the difference between "want to" and "have to". I tend to do some pretty hard core things, I'll take a week off of work for an MMO launch, I'll drop far too much money to fly to a convention to shake hands with the development team. I'll play 4-5 hours a night, sometimes 10-18 hours straight on a weekend. Consume all media available on the game and give it prime real estate in my brain. Then I'll do some very casual things. Stop playing for a week with no notice. Level 5 alts to mid level over some period of time instead of focusing on end game content. Run in circles in town for 3 hours while talking in Vent with my friends. I don't think I could define myself exactly, but in the end I hope I stay more in the "want to" side of things while occasionally treading into "have to" territory. On the other topic floating out there - I make a pretty good living twiddling on a keyboard all day. I'm not gaming, but the only difference is that it isn't fun.
