Most solo devs don’t know this

The process I use generates the mechanical files your engine uses, and those same files double as the documentation publishers require. A vertical slice alone isn’t enough — publishers want the docs first. AGE gives solo devs both at the same time, cutting development time dramatically. As I have already learned this the hard way by pitching my games as just ideas. Publishing companies want to see things on paper first, before ever looking at anything digital. As this is a business and a competitive one at that I don't know why I am telling people this, but it is needed info if one hopes to be a chance at this
