@apontious I'd recommend looking for online #TTRPG gaming communities that regularly play indie games.

Off the top of my head...

Open Hearth Gaming Community #OpenHearthGaming
https://openhearthgaming.com/

Games On Demand: #GamesOnDemand
https://discord.gg/f8wTkSRU

Happy Jacks RPG Network: #HappyJacksRPG
https://www.happyjacks.org/

Magpie Games: #MagpieGames
https://magpiegames.com/

There are a LOT of people playing non-D&D RPGs, but they mostly don't hang out in D&D circles.

Wishing you good luck!

@Dionysus I can recommend three online #TTRPG communities that have active online games and are lookimg for players.

#GauntletRPG focuses in indie RPGs, story-games and OSR.
Https://gauntlet-rpg.com

#HappyJacksRPG is a podcast and actual play network with an active Discord community.
Https://happyjacks.org

#MagpieGames is a an RPG publisher with an active Discord and regular game events: some paid, most free.

I played #AliceIsMissing last night with some people from the #HappyJacksRPG and #GauntletRPG communities.

Wow! What an amazing game!
