I grew up not really "getting" fighting games but in the last few years I've really gotten into them in a big way. Been playing some SF6 recently but my true love is Guilty Gear. GG Strive is what got me into fighting games as a whole and taught me what okizeme and plus-on-block mean.
Lots of Smash fans here looks like, I also enjoy smash bros but if we do have a general FGC it might be better to separate them just so that the two communities don't run over each other. Smash is incredibly popular but it doesn't have a whole lot in common with other more traditional fighting games.
