It became hard to find matches after a while, which is a shame, it was such a fun coop experience. The game would prompt real conversations about the best tool or weapon or ability for the upcoming match, because each choice really would make a meaningful difference in how that crew member played. I get the sense that other games have come along since and done more with the competitive coop ship concept, but the airship theme, the foggy arenas, and the 3D movement created really tense periods of searching and prep followed by stressful, fast paced, but ultimately manageable battles.
In terms of negatives, while the combat feels great and you can really feel success and failure, the maintenance tasks could feel a bit... floaty, which is a lot of what you're doing minute to minute. I feel there could have been better workshop integration but that isn't easy for multiplayer games. Its true that when its playerbase shrank the game definitely suffered. But if you can get 6 or 8 friends interested the game is all there, you can still get a great couple of matches out it.
