I just feel like pointing out that the Rogue is actually not more expensive than the Galleon in Ironium. The 12% extra miniaturisation outweighs the Galleon's lower base cost. Galleons look cheaper in the tech browser before you get to Con 11, but that's meaningless because you can't actually build them then.

(This applies to quite a few other tech comparisons as well, incidentally. A lot of components don't go up in base cost very much, or even go down slightly, as you get better versions... but the early versions are still cheaper than the later ones by the time you *get* to the later ones.)
