Coming from playing Freelancer beforehand and having a pretty good experience, I had a little trouble at first, but once I got the hang of it, it was no trouble at all. The battles are adrenaline-pumping and the difficulty level is just right.
The game even seems to have a bit of continuity between missions, with past choices deciding future missions. So, yeah, I really liked it. And the graphics are pretty good as far as ten years ago goes.
