Would I be completely insane to consider writing my own computer player?
In PHP, the only language I code fluently, but has the advantage of being very portable.
The mechanics of reading and writing data files is relatively trivial (I've already got half that code written for tools on vgaplanets.ca), but the "AI" part of it intimidates me somewhat, how to make it decide what to do. Still, making it do something (e.g. randomly build and move ships) shouldn't be hard, it's just making it play well that would be tricky.
