>>53755154>my understanding is it's basically the same as Time but the story is expanded?Sky expands on the story of Time/Darkness mostly via Special Episodes. There's also a trip up Sky Peak after graduation, a nice little adventure with significantly lower stakes than the rest of the game.
there's also the hack of Sky posted earlier in the thread if you're up for that, but if you dont remember much of Explorers you may want to wait to play that.
