Mobile games are designed like junk-food: take it out, eat some junk, then put it away to go do something else, throw away the bag or seal it for a quick snack later. Normal games are designed like a full meal: sit down somewhere with good atmosphere, nutritious, good conversation, get full and go home with plenty of leftovers and good memories
Bluesky is the first app built on the ATProtocol, its protocol for federation, sort of like how Mastodon was among the first to use ActivityPub after the overcomplexity of OStatus. The ATProtocol is a few years younger than ActivityPub, so its landscape isn’t fleshed out yet. Currently Bluesky caters more towards creators, artists, and social togetherness, whereas ActivityPub tends to lean harder into attracting techies. Both protocols can be run as independent instances, but most people are still using bsky.social for now until more instances pop up and federate together. The process for hosting a Bluesky instance is still undergoing development, but all features of it have been opened up. There exist multiple bridge systems that can interweave ActivityPub with ATProto.
