I'm certainly hoping to see a large ship customizing system for components and appearance. I've recently been playing a strategy game called Endless Space, and the amount of granular control it gives you over even the smallest things on the ship (hull composition, weapons design, shield design, damn near everything) is something that adds a huge layer of depth to the game. Of course, it's not even remotely the same as Everspace when it comes to gameplay, but that's what I'm basing my frame of reference on.
Good luck to everyone, and I'll be getting Everspace 2 when it comes out in December for sure!
