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.

Create one meanwhile

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

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