Just watched your intro, video, and thought this was a good place to say hi. So Hello!

As far as what you should do, I think leaning into what you already love makes a lot of sense. For tabletop role-playing games, I would either look into Livestreaming (DLive), Edited Videos (DTube), or even a Podcast (DSound). My initial reco given you time constraints mentioned above would be pick one format that both interests you and that you think you could do well enough. And there will definitely be people that will be interested. You could even find ways to bring the community into it as NPCs, or something else (similar to The Adventure Zone Podcast if you're familiar).

Anyway, good luck! My biggest piece of advice though, get a profile pic. :) Tons of bots and spammers on steemit/busy/dtube/etc. and profile pictures are a quick way to sort through them.
