Probably because the SNES was where I'd say "modern" games came into being. By this I mean games with complex plot and/or diverse game mechanics etc. The NES had games where we started to see that, like Final Fantasy or Super Mario 3, but the hardware was super limited and the NES was in a lot of ways more like an extension of the old arcade systems, while IMO the SNES was where Nintendo had something that was powerful enough to make games that were substantially different from arcade games.
