PeterKaan gave up instantly.
Nah, he gave up at your place instantly because he couldn't be arsed to play any more. The one I was attacking, he was sending Cruisers (mostly, he did throw a few other things) at me quite often and I managed to try out a few tactics so:
When you say 'definitely' with single SBS, have you even tested that?
Yes, was one of the things I tried against PK. He took it out with his own SBS eventually, which then disappeared because I'm sure I didn't take it out (maybe it's that one fleet he has left).
EDIT: Anyone else having their planets say that Unobtanium/Krellmetal is being produced, but not actually getting any? I've got a few planets like this :S
