I'm pretty sure there was a DDR tourney there last year, it was called Dance Dance Cloudy (or something like that). Sadly I didn't have the time or money to go last year, but I'm planning on attending the con this year and hopefully there will be some sort of DDR or ITG event.

I'm with Gosha. For me PAX > Kumoricon.

Then again, I'm in my late 20's, so an anime convention just doesn't have the same impact it did when I was younger.

I'd go if it wasn't the same weekend as PAX.
