I was wondering if there was a big discord that has a bunch of smaller games on it, mainly with like Silly Games? Kinda like how the Indie Horror Speedrun Discord is setup.

I just got a small silly game (Zippy Detective: Cats) accepted, and feel I would rather have it in a discord like that rather than it’s own.

If there isn’t one, perhaps I could make one? Would it be sought after by some other games?

Something like "Community of small games"? sounds interesting

There's an "obscure speedruns club" discord server, which has a similar premise to what you are suggesting. Here's the invite: https://discord.gg/tXCydaZBBa
