I would like to see all of them :-)
One of the most difficult reverse-engineering projects from that era for me was Stunt Car Racer on the C64 (also ported to DOS). It features a highly optimized 8-bit 3D graphics and physics engine. Fable was the first one that was able to generate a complete port of the game.
Now I am trying of Flight Simulator 4 and Wing Commander 1. Then maybe Frontier Elite 2. So much fun ....
