Subterrans

About

Subterrans is built by Rob Ogilvie — solo, with AI coding agents doing a real share of the work. It's a hobby project with real ambition: to make a colony sim worthy of the one that got me hooked on simulation games when I was twelve.

SimAnt was the game that first made me understand that you could simulate behavior rather than script it, and that emergent complexity from simple rules was the whole point. Everything I've done since in software has some root in that. Subterrans is the overdue thank-you letter.

It's also an experiment in something I've been increasingly convinced is possible: that AI coding agents, given enough architectural scaffolding, can do far more than autocomplete. The game has the rules; the agents work inside them. So far, so good. The experiment page has the long version.

The axpr universe

Subterrans is one of a few projects under the axpr banner — my umbrella for things I build for their own sake. Shared values across all of them: fewer knobs, more substance; short paths between idea and working code; writing things down so future-me can still read them.
