What is a good game were you can pilot spacecraft?

i just want to know of any game were you can fly spacecraft. realistic or not. i have orbiter and i think its the best game ever but i was wondering if there is a fun game where you control spaceships. even if the game is not primarily about that. i dont count controlling spaceships as mouse clicks on a map...so im not lookin 4 any turen a based or real time strategy games with spacecraft.
