It was an ok game, though its balancing left a lot to be desired.
General feeling seemed to be Chaos > Imps due to better designed ships.
Eldar being a pirate fleet was meant to start with 50% of the points of Chaos / Imps ones, what in campaigns was fine as you built up new stuff along the way, but made 1 off games rather strange, Imps vs Eldar owned due to a lot more laser weapons on imp ships giving eldar saves, while chaos ones were more firing solid lumps at ships and then eldar didn't.
Orks were weird as always and later on the introduction of Tyranids was interesting.
I think it kinda sunk though like Man'o'War (what actually was a great game with a lot of balance, apart from darkelf and nurgle ships ruining it).
