The dance after the end credits of Outcast. Pretty cool, and damn well made! Motions seem pretty natural, and they dance much better than I do!
A bit of info on this fantastic game:
Outcast is an action-adventure computer game by Belgian developer Appeal, released in 1999.
Instead of an hardware-accelerated graphics engine, Outcast used a purely software-based combination of voxel and polygons. Makes for much more interesting terrain, at least at the time. I think (pretty sure, well, damned sure actually) they also used voxels for many buildings, walls, trees and stuff. An ingenious use of voxels!
The music has to be mentioned too:
Outcast features a high-quality orchestral score performed by the Moscow Symphony Orchestra and choir. Fitting beautifully with the gameplay, like in a great movie!
The story and execution is simply brilliant! Too bad Outcast 2 was cancelled.. this game was unfortunately never a hit, and the company went backrupt while developing the sequel.
