Back in the days of the 8-bit micros there were some games that were absolutely incredible for what they could pack into a tiny machine. Elite on the BBC micro (32k) was one, but being poor I had a Spectrum 128. There was a helicopter simulator by Digital Integration for the 48k Spectrum called Tomahawk which was particularly good, and another 3D game called Starglider, which was originally for the Atari ST but there were ports to the Spectrum 128 and 48k Spectrum! I seem to remember an article in Sinclair User where they interviewed the developers who explained how they got it all to fit into such a small machine. Self-modifying code and using parts of the frame buffer to store code and data IIRC...
