Some of us have lives, y'know?
I don't want to have my time playing a video game wasted because my kid's asking me a question about his homework and my fleet auto-berserked to destruction or I got a call or an email I need to answer or any of the other million-and-one distractions that happens when you're not just some person by yourself or a kid living at home.
I don't mind a hardcore mode with perma-death and saves only at Stations, automatically, for people who have nothing else to do and want boasting rights, that's fine, but I'd really hate playing a game like this if I personally couldn't go back and redo things. Especially if, as the Campaign gets developed, there are plot trees and the like, and choices you can't un-make. At that point, me personally, I expect to be able to save my character and go back and make different choices later if I want to explore the game.
It's annoying enough realizing that I haven't saved for an hour and that I have to rebuild that 90K and hope that the battleship I wanted and the weapons I need to complete the build I want is in stock, again.
In short, it's fine how it is, and while it'd be improved by multiple saves, auto-save as an option and a hardcore mode for people with lots of free time, these are just minor things. But save-scumming is basically a problem for people who want to play hardcore but can't make themselves do it.
