I just had a thought. Many people loved Mario Builder, (MB) but it's old now, and hasn't been updated in years. Sadly, Ting will never update it again. But, I had an idea. An idea that I'm sure die hard Mario Builder fans would take on. Even though Platform Builder can't use MB sprites, or any pirated sprites, I'm sure that MB fans could create an engine with PB to make MB like games. It'd be like the Mario Hello Engine for Game Maker studio. Only, it's based off of MB, and it won't include mario sprites. What fans can do, is work on MB sprites that have PB style, (or their own style) then someone works on the engine parts. Such as programming stuff for everything to work right. Like bosses, different items, and such. I think PB is capable of pulling this off. After the engine is complete, it can be put on the MB forums, and the PB forums as resources to download. Doing this can sort of expand on MB. But remember, it can't have mario as the main character or anything super close to Mario sprite wise. I'd be happy to help ont his project if anyone takes it up, but I was just sharing this idea to help those sad MB fans.
