Having been a developer of multiple custom engines (including but not limited to engines intended for external licensing in AAA game development), I can confirm that the problems that must be solved for small scale projects are dramatically different from the problems encountered at medium and large scale.

If Amethyst is intended to be a tool for single-developer, small game development, that's great. Carry on with what you are doing.

If you want it to be used for bigger projects, you won't know what you don't know until you actually try to make that big project.

(I assume that Forrest is posting here because he sees potential in your technology, and wants to encourage you to reach that potential. The internet is littered with the remains of game engines with big potential that didn't survive because they didn't take this lesson into account.)
