You probably won't be able to find somebody who can offer an airtight explanation why random homebrew/unlicensed/whatever from 1994 is considered more worthy of inclusion on Person X's list vs. the exact same thing set for release in 2013. The only real answer is that at some point the history book closes and the pages are laminated.
And from a more practical standpoint, people care more about old stuff because it's from a particular era and perhaps has some story behind it and therefore are willing to pay for it. Plus, few people have much interest participating in a perpetual game of moving the goalposts. Does it always make sense? Well, maybe not. But this stuff isn't exactly hard science.
Even if the ludicrous proposition that Nintendo sticks the Nintendo Seal of Quality on Nightmare Busters were to come to fruition, there'd still probably be ample reason and arguments abound to consider it too late.
