What? Hard mode isn't impossible, I beat it the other day. If anything it provides a decent surprise, as I had to spend years playing normal as a kid to get all the medals, and expert actually threw in things I wasn't expecting. Takes a ridiculously easy game and makes it into a challenge on a few levels.
At any rate, I also have Command. The controls were weird as heck at first, but keep at it- you'll adapt to them, I'm sure. They wouldn't work on a WC game because SF is still a roughly 2 1/2D game compared to Wing Commander's true 3D full-range movement. I've gotten all 9 endings on Command- once you adapt to the controls, the game wasn't meant to be difficult strategically, and it becomes fairly easy to hunt whatever you need real fast.
By the way, a certain end path has a certain surprise character waiting for you... further foreshadowing on what may have become of a certain event. If you're a SF fan, it's worth playing until you get to that part.
