Pretty much, yes. I'll admit I was rather disheartened by how badly I was crushed (with +65% damage to awakened empires in total, I hadn't expected to take such a horrible loss). Let the game run a bit longer because I wanted to see how fast I would get mauled... and it turned out it wasn't that bad after all, and I was still sitting on a humongous +3.3K minerals/months, -75% ship costs at the main shipyards, and a 45K mineral stockpile...
I'm going to have to call it a game for a different reason, and it is a vanilla bug of all things that killed it: in the Unbidden crisis, the Dimensional portal changes owners to a different "country" as soon as the first dimensional anchor is built. And the instant I destroyed the anchor it should have reverted, except the trigger is improperly scripted and checks for the existence of dimensional anchors to make the reversion happen. Meanwhile, the event checking for anchors being built still works as designed, leaving a stupidly gamey window between the destruction of an anchor that is not the last and the construction of the next anchor as your opportunity to attack the portal...
Problem: that quasi-invincible Unbidden faction now exists on my borders, and the improper switch vanished my main fleet for half a year because the "portal empire" closed its border the second I destroyed the anchor next to it. Leaving me with seven fleets poised to eat my worlds and not a damn thing I can do about defending at least four of them, by simple virtue of battle length and travel times. And the Unbidden aren't even trying to build another couple of anchors, meaning it's going to be impossible to kill the crisis for quite a while, while I have to play firebrigade against their constant respawns and keep losing worlds by simple virtue of not being able to be everywhere at once against a very beatable foe I just can't stop from spawning because of a bug (I have more than enough firepower, I was just busy on the exactly opposite side of the galaxy destroying a Contingency hub when the Unbidden spawned).
Epilogue is incoming as soon as I can write it..
