It would be great if they could at least bring the runtime to PC so that people could distribute their games more widely - although at that point you might as well have the whole editor too.
I’ve been thinking about this a lot as well. I think it’s doubtful that they’ll port it since MM is owned by Sony. But I agree it would be excellent.
What I’m imagining is something like Dreams that is supported by a whole editor. There’s just something about their approach that feels so much more accessible than any game dev tool I’ve come across. It’s really amazing.
Once WebGPU becomes a reality, it might even be possible to port Dreams content to the web.
