The people behind Wii title Metroid: Other M provide an in-depth, behind the scenes look at the forthcoming adventures of Samus Aran in this 17-minute-long video that offers a rare glimpse into the inner workings of a Nintendo game.
Series director Yoshio Sakamoto and Team Ninja's Yosuke Hayashi explain just about everything a Metroid fan would want to know about Other M in this video from Japan's Nintendo Channel, courteously fan-subtitled by Metroid Database. In it, you'll see the anatomy of a Metroid game, from its 3D wireframe models to the creation of its fully voice acted storyline to the genesis of its simple, uncomplicated control scheme.
Part one is above, part two below. It is fascinating stuff.
