[Spaceships] SS Mecha vs. HT/UT Tanks, and 'ships vs. jets

[vicky_molokh]

Greetings, all!

An idea came to me about trying out Spaceships in comparison to Ultra-Tech and High-Tech. Notably, I'm interested in trying to compare SS-Mecha against HT Tanks (TL7-TL8) and UT tanks (TL9-TL12). No less than SM+4 ones, that is.

Also, it would be interesting to compare HT and WWII planes to those doable with SS (i.e. streamlined non-space-capable craft).

I'm especially interested in the mecha part of the comparison. Anyone tried that?

(I'm assuming that enabling superscience is allowed, but improving superscience should not be, unless it's a last resort.)

Thanks in advance!
