Nintendo has had a very good track record when it comes to transitions from 2D to 3D, with Super Mario 64 having an average of 94, Ocarina of Time 99 and Metroid Prime 97. So, out of these three, which one pulled it off the best?

Why is Metroid here? That 3DS game is just a spinoff >>

? Why wouldn't it be?

Spinoffs don't matter - it will suck anyway, come on- FOOTBALL >>

Tough choice, all 3 all great.

Not much of a Metroid fan but I voted for it, as aside from the perspective it largely remained the same. Zelda handled it better than Mario, it still felt like a proper Zelda even if it had some changes. It may be better or worse for it (depending on who you ask) but they still feel like the same franchise.  But Mario felt like a completely different kind of platformer in 3D.

Mario remained great in 3D but out of all of them, it changed the most in transition. 

I think Metroid by far remained most true to 2D versions. Both Mario and Zelda were quite different games in 3D.

pls dont tell me you are being serious. Personally i say metroid, because metroid prime was like the best thing ever

All three were unsatisfactory in my entirely not humble opinion. Metroid lost good platforming and vertical level design, Zelda lost nonlinearity and exploration, Mario lost linearity, platforming focus, and started recycling content. None were good transitions for their franchises.

Though not technically a 3D platformer, but an isometric one, it gets closest to the core of the franchise while sticking to a 3D plain, so after almost 30 years, I think the only one to make a 100% real transition is Mario. Followed distantly by Zelda only because of Wind Waker. Followed even more distantly by Metroid because of the obvious Prime.

EDIT: I shocked at how many people think 2D and 3D Metroid are similar. They aren't. Like, not at all. Prime is great, but it isn't Metroid. One of the best games of all time. One of my top 5 games of all time. The best first person game of all time. Not real Metroid. It literally plays nothing like those games aside from the level progression system.

To me its mario... after it went 3D, I felt this is the future of mario, there shouldnt be 2D platform marios anymore.

What happends? new super mario bros, and super mario world 3D.... /sigh.
