Well in this case, I would have to go with Super Mario 64. Athenian200 did bring up a rather good point about how a 3D could be made. I mean after all, SM64 did come out before Ocarina of Time, so in retrospect the games that were later released become more "polished" as athenian200 put it.
Believing that looking at how SM64 was done, could've gave Nintendo(example) of how the games' style should be better, and what I mean by style, I mean the whole aspect of the game. While many say it's Ocarina of Time's doing, I believe it was SM64... in which case, look at such non-motion and very polygonic SM64 is, and see how two years later to the release of OOT to find more motion in the video game, which then gave even more motion two years later to Majora's Mask. This case, look at how SM64 helped change this style of gameplay to later realeases of other games.
Bottomline is, SM64 did more for video games in my opinion. This is just what I felt it has done.
