So, I've been thinking a lot about it, and I think I've finally accepted what I always knew, but didn't really care. I've been concentrating too much on writing an engine, which is fun and all, but it's not going anywhere. This is perhaps because the goal is elusive.. a moving target even, the closer I got, the newer more advanced thing I wanted to add... there was a lot of work, but not enough direction, no vision.
So I've decided that I'm going to take what I have, do a quick evaluation of what stays and what goes (I already have a pretty good idea what that is) and I'm going to move in the direction of writing a game.
On the game design side of things I already have an idea, an idea I like quite a bit, so I'm working on evolving that idea into a design. Currently I have a page with a story overview (I'm keeping the story light, but I do want some story elements) and a couple of mindmaps with ideas and structure.
Hopefully, I'll be able to keep this simple and finally evolve SGE into something more real.
