Noctis IV is something I always love to play, there's no sound and the resolution is dismal but it's a blast once you get a handle on the controls. I use the bootdisk someone made to run it;

Can fly around, harvest fuel, walk around on the roof of your craft, reset the computers after you fly too close to some systems, get stranded, drop down to the surface and check out strange surfaces and oceans, check out seemingly perpetual storms on some planets, try to find your home planet, and take pictures, among many other make-your-own-fun style objectives.
