Especially since if you don't complete one tiny objective, you have to re-fly the whole thing. Fortunately, this, as well as the aforementioned mission bugs, have been fixed in a recent patch. I'm reviewing the boxed copy here, though, not the patched one. All in all, LucasArts have crafted an excellent game. Nothing's perfect, and greatness is subjective, but if it's Star Wars space combat at its finest that you want, then you can't go wrong with X-Wing Alliance.
Patch fixes most qualms.
Some mission bugs, strict mission requirements can be tedious, A3D nsupport not implemented.
