Maybe the ROI is the feedback and such from the community that has popped up around the game? That, and the $15.00 per copy to get access to the source code as the series goes on. But I'd be willing to bet that the feedback and community is the driving thing for this guy.
My understanding is that Casey was specifically bothered by newer game programmers not understanding the underlying internals and writing slow software. Seems like he wanted to do something about it and this was his expression and attempt of doing so!
