Just wanted to say that I've played the final Retail version.
I'm afraid that I feel the game is less than the sum of its parts (which is ironic, given that it's a game about building spacecraft out of bits and pieces of other spacecraft).
Certain aspects of the combat gameplay were tuned really poorly, in particular the "Synergy" system, which doesn't actually improve part performance enough to justify losing slots that could be devoted to more weaponry. The math just never works out; the only thing where this isn't true is with engines, where Synergy actually does work as advertised, but even there, I found that simply saving up Scrap to buy faster engines was the path to efficiency.
The escort-fighter concepts are really, really, really broken, too; there's exactly one "right answer"; the rest of the fighters felt like they were just there to give players easy opponents. Even in the campaign, where the number of Command Points is pretty limited and level-grinding got really painful, I found that it was easy to get to the point where my escorts could kill most things, including AI capital ships, without much help, once I figured out which ship / weapon combo to use.
Basically, it's not terrible, but it's not "Mount and Blade in Space" as many people said in their Steam reviews. Or maybe it is; I've tended to forget just how broken the balance of the core M&B was, before mods got it fixed up and made it less about just getting enough Huscarls, lol.
But in the end, it feels like a game where a balance pass or three would be really beneficial, but it's been in development so long that I expect Minmax will want to move on pretty quickly; it had to have been pretty resource-draining to produce.
