while some of that is true (Scratch Kart and some collaborative studios,) I am not a game developer on Scratch but more instead as an animator since I've never made any games on Scratch but lots of animations you might wonder why Scratch Kart is thought to be a game, well ideally it is more of a "What If..." when Scratch characters are in as a "racing game" style similar to Mario Kart but it isn't a game (yet, probably one day as a whole different software Scratch Kart will be a game but we're more focused on a render/animation style similar to Mario Kart at this moment in time)
