Just thad our third win yesterday. First was a solo win, the next two were duo victories.
First time with spire campaign. Those ships are pretty awesome. Very very powerful. We only built one city, because by the time we got to that point we could just roflstomp the AI with our spire ships so we decided to just go for it. It took us 24 hours or so. And it was a 40 planet map, with 7.0 difficulty. Pretty long, but that's how we roll!
I did want to finish the spire campaign, but looking at the wiki it seems we were far from completing it. We'll have to try in our next game.
Martyrs and Jumpships are the best SpireCraft ships. The former are just awesome autobombs in limited supply and the others are fantastic for transporting the spire ships =)
Imo, definitely the best expansion so far!
