interesting analogy. there will, of course, be things the two-player mode can produce because there's more fingers on the piano keys. I can not physically play 15-20 keys with my two hands, but two players easily could. And... it probably sounds 'better' in some regards - richer/fuller/etc. But... it's going to take a lot more practice for people to work that close together physically. There aren't, AFAIK, a lot of piano pieces written specifically for two players - but that may be more a function of my limited knowledge vs something inherent in piano music.
