My god, this thread has digressed since I went on my short little holiday
Anyway, about planetary assault options: I haven't really used any of the more imaginative ones. They are hideously expensive, and I'm just too cheap to use my money on killing aliens, when I could use them to buy big pretty space ships. Of vourse that also means that I have yet to invade a planet, where the odds were not for me. Probably I would spend the money if it meant the difference between winning and losing.
