I’ve not seen a community that fits your description yet, although we’re probably just not big enough for it to be needed yet. If you’re looking for people to play a specific type of game with, the communities for those games / genres will probably welcome you posting about it because all the new communities want content and interaction. It’s only once they grow past a certain size that they’ll start to filter that stuff out and new places will be needed.

You could create a community for it if one doesn’t yet exist

Create one meanwhile

Make it! I’d join. I’m looking for gamer pals
