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.
@WandererUber yeah there definitely needs to be some bigger games to come out of it. pretty much everything out so far have been like, game jam games afaik.
