Quoted from HoakyPoaky:AFM & MM are like flipping a coin. Both classic, similar mode-based code, fan layouts, same designer. I am not made of money, so IMO it's not worth it to me to own both. I'd I had to pick one, it would be AFM without a doubt.
BM66 has Lyman on the code. Nuff said. Deep, balanced modes, good variety, challenging, always fun. You'll get years of enjoyment from BM66.You've already answered your own question
Lyman coded both games. So not enough said? Haha
