One thing to consider is how the late 90's-00's game are without a doubt the best of their time, while before there was so much fucking choice that votes split among their favorites.
Just look at the console voting for a more clear view; there are so many JRPGs that people like that after #6 the votes split completly... we had votes for 255 different games... 119 of them with only vote. It's as if each voter liked 2 games that no one else voted for! That doesn't mean there aren't good JRPGs besides the top 10, but that each of them pleases a different kind of player, and each person has his favorite.
The PC list is the same thing, while Fallout is almost konsensus with 189 votes, Desu Ex at #12 has less than half the votes... is not that people don't like older games, is that everyone likes a different one.
If we did a franchise voting, no doubt that M&M would score very highly, but it's hidden on the list due everyone voting for a different game of the series, same thing that happens with Pokémon on the console list.
Good point.
