I mean I guess rpg paper maker is a thing but I imagine it has way less features compared to rpg maker so meh
There are other options out there, but none of them come close to the established history and community of RPGMaker. Anything at all you might want to do in terms of a basic RPG has probably been tried there, discussed, programmed around, etc. The community and decade of documented experimentation IS the product, as much or more so than the engine itself. Which is why this is such a blow.
