I just saw a video about Zelda TotK & it looks like you can make your own vehicle plans. How long 'til pretty much every game has an SP-like builder within the game where you can make any vehicle & just play the full game like that?

Would SP be better as a plug-in for something like Microsoft Flight Simulator, where it just exists in the simulator? I think this is overdue while it might eventually kill SP, which I still love even tho I haven't played in a long time.
