Hi! Welcome! There are a lot of sports teams and a lot of games so game threads are usually made on as ad-hoc basis. It’s kind of up to you or the mods of your community to make them.

We have some mods in the !cfb community that make game threads every Saturday. The auto created threads that are created on Reddit require someone set up and maintain a bot. I ran some bots for the baseball communities for a year and will likely revive some this year.

Hope that helps!
