I'm sure everyone knows that Arcadia runs the Tougeki series of tourneys for fighting games. Try parodies this by running tourneys for relatively obscure games every 6 months or so. The next one is happening on November 12-13 so anyone in the area might want to check it out.
Here's the schedule from their blog
Super Bishi Bashi Champ
Soul Calibur IINovember 13
The Fallen Angels (I'm probably going to this, EDIT: can't go, won't be in town...)
