Maybe so, but in my opinion it's influenced the worst in gaming. And by that I mean fucking two weapon limits and regenerative health! Aaaarggh. It may have helped Microsoft, but purely in my own opinion, Mario 64 was far more influential as a whole, and was the first decent (and arguably most successful) 2D to 3D translation ever made.
And that moment in 1996, playing Super Mario 64 for the first time? Using an analogue stick and having that amount of freedom in a full 3D world for the very first time? It was an industry first, and simply unlike any game ever made before it. I have to say, it was simply awe-inspiring. I never got that from Halo, after playing Goldeneye for three years prior to it. Halo was just another shooter. Mario 64 was a revelation.
