I think Stacker news model could be interesting for games, but I'm not sure.
For games users could create levels / maps / mods and upvoting with sats would be used as the bot-deterrent filtering/rating system.
Stacker news being centralized is a good thing to ensure the system cannot be gamed (opposed to Nostr in this case - where zaps can be faked).
Being realistic though, the game has to be good enough on its own that people play it. Bitcoin doesn't fix that.
I'm wondering if the game is good enough already, then users happily play and build content on it for free.
Does bitcoin solving spam/bot content really make the game much better?
