All three are masterworks, and among the top five launch games ever made.

For question number one, Halo slightly edges out Super Mario 64, but only by the slimmest of margins.

For question number two, Super Mario 64 edges out Halo and SoulCalibur. It's one of the most revolutionary and important video games of all time, and one that best represents the unprecedented freedom of movement and camera control achieved during the early fifth generation.

Super Mario 64 was revolutionary. And it's a brilliant game on top of that. All three of these deserve their place in the hall of legends though, and answering Halo is certainly not 'incorrect'.

Personally I'd say Super Mario 64 > SoulCalibur > Halo: Combat Evolved.

By personal preference any way, I'd still say Halo has more importance than SoulCalibur in the grand scheme of things.

Mario 64 is a far better game than the other two options so it easily gets my vote.

Super Mario 64, hands down. That game is the definition of revolutionary.

It's not even close at all. Mario 64 is objectively the greatest launch title ever.

It perfected the formula of 3D platforming and 3D in general. If you've ever used the right stick to control the camera, you can thank Mario 64's camera system for laying the groundwork.

I voted for Halo because it was good enough the make the OG Xbox survive and become a major part of the industry.
