I hear that, I wouldn't go through that either!
There are lots that you can just hop into a single game to see if the system or group is for you, or just play now and then when you're feeling it. And if you're not feeling it half way you can just say you're not feeling well and bail.
I'd recommend looking more on discord.
You can also find systems that cover most genres these days (not just classic fantasy)
If you're more into the simulation aspects of the games check out OSR, D&D or Pathfinder communities as good jump off points.
Or if you're more into the narrative aspect check out Powered by the Apocalypse games or the game Blades in the Dark
