Well then I guess I won't play BB or P4AU or GG Xrd if that dude doesn't want more people playing those games.
Or you can you know listen to what was said yourself, think about it, reach your own conclusions and not let people form your opinions for you.
What he actually said was that the influx of new players will have a really difficult time because there is an entrenched core croup, like with all niche games with a high skill ceiling, that will beat them over and over again. Its going to be extremely demoralizing and it would actually take a lot of time and effort to become competitive.
This of course applies to every fighting game scene ever. This kind of thinking also applies to any entrenched group of fans of anything that has ever managed to spawn a fandom. Hardcore fans assume that casual onlookers don't have the dedication and drive to reach their level of proficiency and familiarity with whatever it is that it may be.
But yeah you can also just never play those games. Everyone has better things they could be doing instead of wasting time on video games.
Edit: The reaction in this thread effectively proves the point that even a hint of resistance is met with equal amounts of hostility and ignorance.
