I always adored the adventures Dynamix published with the help of Sierra and the endearingly cliched Heart of China has always been a firm favourite of mine. I loved its atmosphere, graphics, rather silly plot and even the puzzles, but never played the 16-color EGA version.
Anyway, if you want to own a complete and lavishly boxed version of the game, there's a lovely copy of Heart of China (MS-DOS) for EGA, CGA and other less colourful graphics cards. It comes complete in its box with all the 3.5" disks and the ton of documentation that originally accompanied it.
