I go to game, alot. Its a chace to game for almost 72 hours, with nothing else to worry about. No work, no wife, no daily routine. Get up, find a game, play till I passout, get some sleep (usually not a whole lot) and then get up and do it again.
Its also a chance to hang out with my friends, since I have moved its a chance to game with my old group (gamed with them for 10 years before moving 3 years ago). I also have gamer friends that I have met at the Con I attend yearly and only see the one time a year, some of them for over 15 years now.
Iv'e recently also started using it as a chance to play other games that I haven't gotten to play in a while.
Oh, and I do a little shopping at the small dealers room they have.
One thing to add, the Con I attend is a local con that focuses on gaming. (they average about 2300 guests total each year) They don't have guest speakers, or costum contests or a lot of the other things some of the bigger cons have. They have a varitiy of RPG's, Board Games & Mini's games, they also have a group from the SCA that do lectures and Demos, and a few semiars/disscussions about gaming and the industry.
