I used to stick with Discord for most of my group gaming until they changed a bunch of policies and the overall vibe shifted. Now, I’m mostly on Matrix for chat and dice bots and sometimes set up Jitsi if we need voice. The flexibility is nice and feels less corporate, like you said. IRC is solid if you don’t mind something simple, and I’ve even tried hosting with Galene, which isn’t too tough once you get the basics down. On another note, when I want something different from the usual TTRPGs and MMOs, I check out iSabong sometimes since they offer more game variety plus live streams. It’s a neat way to experience games that aren’t usually online.
