Sadly, too large to die. 99% of content creators willl stick to what the majority use. I'm just using Grayjay (Android) & Invidious (desktop) to watch all my content.

Fighting games can be tough given the smaller community. If you are in a larger city then you might have access to a fighting game community. If not, I tend to message other players to see if they wanna play more after a ranked match. It may or may not turn into chatting but getting to play 10+ games with one person can be quite fun. If you're willing to travel, there are large events hosted for fighting games too. Most people show up to press buttons and have fun even if they lose in the tournaments.
