How do you do that, Dragonlord?

[Dragonlord]

I liked the combo of Rock/none with Advanced Storage Techniques when Shoujo mentioned it to me (the moons! of course !) but now I am in 3 games with that race setup, and seems like *everybody* is doing it now, which causes a lot of competition for planets. It also makes it harder to find a human player you can exchange colonists with (cheap way to avoid atmosphere converters), and I sometimes have a hard time convincing a Gas player that his Gas tech is worth less than my Rock tech, (in a trade) because I cannot get breathable Gas planets while he can get breathable rocks.
