As a gamer who grew up on Flight Combat Sims, like FreeSpace (which remains my favorite game), I always had a soft spot for the space missions in this game, even if they are rail shooters. I'm more than a little excited for the new space content, just hoping it brings in new environments instead of the same three re-hashes. To those who had to "read the boards" to "figure out what was going on" because "it was displayed so badly", I suggest getting a new screen and graphics card. There may not have been much story, but its pretty clear that the objective was always "Shoot what's shooting at you".
I too have been trying to figure out what that poster meant. Unless you're flying with your mission objectives hidden, I can't think of a single space mission that would be that puzzling even on your first run ever.
