I'm assuming not. I'm currently testing all of my functionality through a tutorial function in the main file.
I just thought there would be possibly be something to it that I wasn't seeing, such as:
-How to make it more fun
-Studying things that I will need to know for building graphics, engines, AI, etc.
But you're right. As far as testing goes, a main loop isn't really going to add to anything.
I also thought I'd put a post up here just to be part of the community.
