Anyone ever play StelCon? It's at least 10 years old. It's a turnbased strategy game, and IIRC stands for Stellar Conquest. You play on a 10 by 10 grid, with ~15 planets of variouis quality (like terrain in civ). Your planets produce ships and credits (for tech) and you battle other humans/AI. IIRC Conquest was the only victory option.
