I have literally just got round to playing this myself. It is a stonking game though the side missions can get a bit repetitive you keep doing them regardless for the XP. Some of the planet landscapes are amazing, if you have the gpu to match, particularly the extra downloadable content asteroid based mission. The quality of the enviroment on that map you could imagine that's what it would look like if you did land on an asteriod. One thing that bugs me though, I haven't found a way to fully switch off mouse acceleration whilst on any 3D part of the game, its seems hard coded somehow, probably a result of of the console port. Mouse is fine in any of the 2D menus, just in 3D it turns acceleration on.
