Most of the screenshots dont looks as pretty as some of the ones they gave us before
Hehe, dont worry GreatEmperor, they are getting better with every new submission in the screenshot post
Here are a few little screenshot pointers for everyone

a)Use the pause button and zoom/move about to get the best angle
b)Use CTRL+Shift+Z to remove the UI
c)Don't forget the action! Get some fighters & explosions in there for extra flavour.
d)Feature a dominant element in your composition. For example, a close up of a structure, with ships in the distance.
e)Go to menu > options > graphics and adjust your quality settings.
