i was thinking about doing something like that but there doesn't seem to be alot of interest around vam for gaming, especially tools, from what I gathered.
I released AETools with VNs in mind, even made a demo for it
but i don't think anyone even attempted to use it lol. i have also save game logic and a sort of database logic but never released it, it's in my older vimeo videos. I figured i'd get more headaches releasing and trying to support it. IMO the learning curve for vam is too steep for most people to go crazy creative with large scale projects and it would be a lot of work for a very very small group of people to do a tool like that
