It would integrate in the games themselves, so the question what would games for Nostr look like is also a good one.

i think we all can imagine services like steam based on nostr (would be awesome to buy indie games in btc) there users can support creators and pay not only for dlc but also affect on adding new features to the game by pay-for-vote polls.

and services like discord with those private rooms – it’s also a pretty nostr-like thing, isn’t it?
