I think the easier question is, what didn't TIGJam do for me?
I wrote a lengthy blog summing up my experience:
http://phubans.wordpress.com/2010/11/02/tigjam-3/Honestly, I'm hard-pressed to find a better experience I've had in life as of yet. Game are my passion and my life's dream, and it was very validating to see Madhouse go over so well with the crowd there. It was great to be around so many brilliant, creative, and like-minded people who got my references and jokes. It was refreshing, exhausting, inspiring, and overall a great experience that changed my view of life.
For the past couple years, I thought my life might be coming to an end, but as I looked up at the stars one night near the last day of TIGJam, I thought perhaps it's only beginning.
