Well, I build ringworlds as the ultimate defense against people detonating my stars. I don't give a darn about their production or population, but it's incredibly difficult to survive the reqired one round of combat against the volume of fighters and weapon platforms I can stick on a ringworld. In my games I bump into the 2000 unit in space limit a lot because I over deploy mines. And I do play against humans so stellar bombs get used. Stick satelites in orbit of the star and he just waits for the 30 turns to end, then kills the system. But with a ringworld, he's toast and my stars are safe.

I'm about to test an old strategy I used to use when my friends and I would play for points in Finite resource games: Blow up all non-huge worlds and rebuild them as huge. I'm wondering if this resets the resource limit on the world. While I'm at it, I'll test to see what the resources of ring and sphere worlds are in finite games. I'll have the data for you on Monday if no one else does it sooner (I don't have a connection over the weekend).

Also, if you're playing for points, and not just to win, sphere's are worth building.
