I would love to see a Metroid game on the same level of fidelity as the zelda tech demo. It also got me to thinking about the controller with a Prime game, besides, retro did say that they were working on something...

Moving the controller around the environment to zoom/scan on things.

Drawing on the map with your own notations.

using your own hands to punch in codes on samus arm ala predator???

What kind of pie in the sky ideas do you guys have?

Disregard Zelda, Aquire Triforce.
