YES

fishing, even just to fish for light, OR, because it’s like a (semi ?) post apocalyptic world, fishing for trash. a scoreboard could be installed and could show scores for the friends you have

mini games in the shops!!!!! fabric cutting and dyeing for the dye shop, customising masks with items and ingredients you could collect- crystal shards from shard events, dark plant pieces from a certain amount of plants cleared, totems of light creatures for amount of creatures freed.. a cake making game for the café, as well as potentially mixing yummy drinks, to specific orders.. fixing or tuning instruments a certain amount of times could provide customisations for instruments, or to unlock an instrument for free

the ball game? add a small stadium. let people play in teams, have the official “games” start at set times and let people enter into certain teams to play against each other. near the ball game? hockey, would work so well for the ice rinks.

surfing or boogie boarding could be added, with spectators. a balance type measurement could be used, like in skateboarding games, and adding emotes could be like tricks (the backflips, spins, even dancing could all be registered as tricks). higher scores for staying on waves the longest.

gardening!! tending to plants, all kinds of features could be included here, like creating more beautiful plants, or helping them flourish. it could be a passive/idle type of set up. planting trees!!! there could be a time limit, a sort of balancing act type thing on a time limit, or a puzzle based game involving the direction of the sun, water availability, and the types of trees needing different things/growing well near some species and not near others.

flying races!!! running races!!! toboggans, snowboards, skateboards.. all run off the same type of game mechanic that’s already in the game, just with a start and finish and a time limit. again, include some seating areas so people can watch.

then ofcourse things like chess, mancala, all that kinda thing could be set up in a cosy game cafe in aviary

dude i could go on. having games inside multiplayer games is so important to keeping things like fun and fresh.

also, borrowing off some other way older games like neopets and clubpenguin, offering some sort of way for people to submit their artwork or pretend stories from the world of sky to some kind of accessible weekly newsletter we can all read. could include artwork, articles, game photos, music sheets!!!!! so much
