Well, I had a victory screen upset last night, as much as that really matters. I was beating the fallen empires by a few thousand points and the victory year was closing in, when suddenly... the butterfly people of the militant isolationists vassalized another fallen empire and added
12,000 points to their score. Then they did it to another one! Victory was stolen from me at the last moment.
The only consolation is that the crisis finally triggered in 2480 and they can't
actually win until it's over. I'm tempted to let the Prethoryn Scourge eat them so I'll win anyway.
In seriousness though, I'm just happy to see the Scourge since this is my first time with them. I'm not really sure what to expect, but I'd built my fleet up to counter the Contingency and I'm worried that a shield heavy fleet isn't going to fare well. I've got about 600K fleet power with ~15 levels of repeatable military techs of every relevant kind, and the crisis difficulty is 2.5x. I'm fairly sure I'll be okay, although the Scourge hit the galaxy in a spot where two hostile empires are currently preventing me from responding to it, so it might spread a lot before I can engage it, and unlike the Contingency, I'm led to believe that can make the Scourge substantially stronger.
Edit: I'm also unsure if I should bother with titans. I left enough unused command limit in each fleet to add a titan, but my experience with the Contingency is that they don't last long enough to be worth it. The Unbidden were a different story though, and I don't think I lost a single ship beating them back. So... maybe they work for the Scourge?
