Fighting games. Mainly Skullgirls (Val/Robo/Para) and Them's Fightin' Herds (Velvet), I've also been getting super into Under Night In-Birth 2 (Vatista) now. Put together
this lovely custom stick last year to retire my old Hori RAP4 of seven years, and I'm really happy with how it came out.
I also play a lot of Riichi Mahjong. Mostly online (Master 1 on MajSoul, 5th Dan on Riichi City), but I'm heading out to a local tomorrow to start playing some IRL games.
That might sound like a strange venn diagram, but there's more overlap than you'd think - we actually have a group that brings tiles out to major tournaments to get some friendlies in. FGC majors are really just conventions that happen to run brackets, and so we'll have all kinds of other activities going on too.
