That would akin to discounting Quadrun and Crazy Climber from a list of good 2600 titles and I don't think the Atari fans would like that now

So MiM stays... it's an excellent game, albeit one laced with the usual Apex difficulty, and the Rowlands sold many thousands of copies (although John was reluctant to tell me exactly how many when I asked him years ago). In fact you can now buy it new again in a special 15th anniversary edition over at Psytronik Software.
