Some scenes were noticeably pixelated, but this really can't be helped until the compression and playback technology improves. It is just too bad that these clips are the best thing in the whole game. The real-time 3D engine was unimpressive. No matter which mode you choose though, about the only thing that changes are the sizes of everything in relation to you and how much you actually see. You could be going up a mountain and barely notice it.
Rivers are just a blue band going across the screen.
Dry land came in various shades of green and brown, with little distinction between one color or another. The quality of the graphics never came close to the great screen shots that were found in the manual. As for music, there was none. Well, there's apparently supposed to be MIDI background music of some sort, but nothing ever came out of my Gravis Ultrasound sound card. At first I though it may be a configuration error, but I can get MIDI soundtracks from every other game I have.
