Good question. This is just how I see it. I’m sure there is a ton of other stuff too.
Either regularly host gatherings or be in regular attendance of local gatherings.
If you always beat a local that is serious about leveling their game up, tell them why they’re losing. Helping people you play with regularly level up their game is not only good for them, but good for you.
Attend most every legit local tourney you’re able to, barring important non-fighting game commitments (of course).
Encourage other local fighting game fans to attend gatherings and tourneys, IE, promotion.
Honestly, this sort of thing is something every fighting game player should strive for, imo. I’m hardly a top player, but I make every effort do the above. The fighting game community starts with a strong local community and radiates out from there.
Attend every major you possibly can. Although it’s quite a commitment–both in time and money–for players to travel across the country for tourneys, it really does a lot to hype the tournament locally.
Try to get high quality locals from your region to travel more.
If it were me? I’d try to find a way to make a regional with top prizes being plane tickets to majors. Tickets can be damn cheap if purchased early enough.
I think an important thing too is–just like when fighting a match–play to your strengths! People like Ultra David, James Chen, Viscant, etc write well, so written guides from them are always helpful. The alphaism crew do a great job of putting together an entertaining, yet still informative podcast. The four bosses are obviously strong at event planning.
What I’m getting at here: ask yourself what your strength is. Do it. If you suck at writing but are good at one on one teaching, do that. If your home situation doesn’t lend itself to hosting, go hang out.
Just remember though, keep it light. If you find yourself burned out, take a breather. Even though the fighting game community is as close as it’s ever been to, well, “reaching the next level” it’s still really a hobby for most people.
