It's a PC game from the mid to late nineties. You're flying some kind of aircraft, looks like something futuristic and I seem to recall the ability to fire lasers. You were able to fly around a fairly large world with a textured landscape - lots of grey skies and green hills. Two things stand out - one, is that (early on at least) there appeared to be zero enemies. In fact, I don't recall fighting anything. All I seemed to be able to do was land within a rather large mothership, which also flew around; but that also seemed a pointless exercise. The second thing is that it had a pretty good EDM soundtrack.
