I just won a five-man local bracket for I play a lot of Riichi Mahjong at the local club as well, but haven't been able to make it out to a proper tournament yet.
I also play Skullgirls and Them's Fightin' Herds online, and have been to a few tournaments in the past, but they don't have local scenes around here anymore. One trip a year traveling out to Combo Breaker is the extent of my offline play for those games.
