There's a great Arcade Expo in Louisville coming up in March. I'll be there. It probably doesn't have the awesome "celebrity" guests that magfest has, but it's a damned good time
Honestly the celebrity were cool at Magfest, (Also being part of SiIvagunner I guess I was kind of a 'celebrity', as they were an invited guest) the best part was just hanging out with friends I saw irl for the first time, and meeting new people. After almost all the Siiva people left to head back home on the last day I had dinner with some people I just met and was hanging out with.
I could have gotten some more signatures, a friend got his Sonic Adventure LP signed by John St Jon and he wrote 'Dam! I'm Big' on it, but I preferred to walk around than wait in line again after the Sonic Composers. I also missed an opportunity to meet Extra Credits, ChrisChan and Chad Warden.
With most famous people you get maybe a hello and a picture, but the memories I cherish more are from hanging out with people.
