RPG In A Box has a gofundme going to help with development costs and they've only made just over $1,000. The guy has been working on this engine for over a decade and it has progressed so much and it's such a neat thing with so many features. It's kind of sad to see all of that effort go mostly unnoticed.
@icedquinn I haven't had any issues with crashing but I've only just recently started using it. There's a demo and even a web app demo now too. I love the voxel editor, the fact that you can build models within the engine itself like that is awesome. It supports steam workshop now too so you can grab models that other people have made. I've uploaded a few! It's just a cool program.
