I've seen r/gamesociety fail and die out on 3 separate occasions. And to be honest you're making all the mistakes mods have made there over and over. If you continue on your plan it will fail just like every other time because you (like your predecessors) are totally misunderstanding what makes these kind of groups work.

Over the next month you've scheduled thousands of hours of games to discuss. Nobody can keep up with that. At the absolute most, people will get through maybe two of those games in that time period. And that's if people are willing to devote 100% of their game time on keeping up with your club. What you've scheduled is just another place for people to discuss games based on their past playthorughs. Which is fine but there is hundreds of places to do that on the internet even without leaving reddit.

If you want a steady group of people to develop you need to focus on 1 single game at a time. Game/book clubs are about the process of playing through in a similar timeframe and reflecting together. Pick an older game that many many people have access to. That's how you'll build a community.

You have 7 people online on the sub in peak prime internet hours in the US. You're mad if you think that's enough to maintain interesting discussion. I'm not here to poo poo your idea, I've posted this message to r/gamesociety mods during several sub reboots. They've never listened and instead flooded potential community members with options.

You have more threads scheduled for this month than you have users. Seriously ask yourself if you think that's going to work.

If you make the changes you need to I'll participate. I've tried in the past only to watch the sub wither and die. Pick one interesting game. A game that hasn't been talked to death already and go from there. Expand later if by the grace of god the sub doesn't die again.
