Platform Builder has advanced so much since even the beginning of last year. (2018) It has advanced so much, I personally don't believe it is a mere level editor. But rather, a professional game making tool. As I say in my stuff about PB, "Platform Builder is great for casual game makers who just want to make a game for fun, and great for serious game makers who want to make something as complex as Super Mario World." I believe this is true. Though at the time of this writing I haven't revealed a lot of the new mechanics, it's constantly becoming more and more complex like SMW. Though PB hasn't arrived yet to it's full potential, (it's still missing lots of useful things. Such as a HUD editor, mouse clicking stuff, etc etc.) it's getting very close. I believe that in the next 5 years, PB will be exceedingly complex and good enough to compete with Game Maker Studio 2. Mario Builder was a nice little project, but Platform Builder has out-done Mario Builder by like...100x. TingThing has said that PB was supposed to be similar to Super Mario Maker. I believe that it isn't at all like SMM. Due to the fact that you can edit almost anything, and make it your own game. Instead of simply using pre-made tools. You'd have to have an extremely large game that takes years to develop to put in all of the possible tools you'd need. Though people are expecting Super Mario Maker 2, Platform Builder has already outdone it. And TingThing has outdone himself time, and time again. PB 7 is sure to be a well known hit in PB history.
