Super Mario 64 was the second game I ever owned, and the first adventure game I ever owned. I've never enjoyed a game more than I enjoyed Super Mario 64. Being a younger gamer, and not owning a NES or SNES, Super Mario 64 was that game for that got me into video games, just that sort of game that only a child could adore. I still adore it now, even if it's control mechanics have been perfected in more recent games, it was a gem back then, and through that, it remains a gem now.
Super Mario 64 DS was a nice revisit to the world, and I think it was nice to re-experience it on the DS. The DS version is equally as awesome.
