Instead, someone could see what games their friends are playing (ex: bobby is currently in a Minecraft world, Susie is in Roblox, Johnny is in a Fortnite game), and click a button to join them not just in the game, but exactly where they're playing. Think Zap Stream but for playing games rather than watching videos. Nostr could be invisible in the background, and all the user sees is a game launcher/browser that starts with their friends.
