The reason you don't see quality like that in games (although honestly we're only a couple years off from that) is that generally games operate under
a different set of conditions and requirements when it comes to generating and animating art content. To begin with, all art/animation must conform to
the maximum levels of performance, and to do this they utilize a number of tricks and 'hacks' if you will to 'emulate' visual factors apparent in much
higher fidelity mediums.
For example, a pistol in your favorite FPS game may have lots of nobs, ridges, bevels etc. all over the gun. Odds are, the gun itself is a very low
polygon model with several 'skins' wrapped over it that contain light vector data (as well as color, texture, etc), so when light rays hit the gun it
displays the illusion of depth amongst the 'ridges, nobs, bevels' without actually having to utilize the 3d model itself to make those calculations
(which if it did would increasing the amount of polygons on the weapon, which reduces the total performance of the game itself).
Therefore, since current technology, ie. consoles and home computers, don't have the power to render extremely high polygon models (like the alien
video linked in the OP) in run-time (which basically means the machine has to do all the thousands of mathematical calculations as you're playing the
game without slowing down the framerate, which coincidentally relies on the same hardware calculations to render the images to the screen). If the
machine has to spend 3 hours rendering out a model with 2 billion polygons (not an unusual amount after several 'smoothing' passes), then concurrently
your framerate while playing that FPS will be something like 0.0166667
Of course, if you're aren't constrained by time, you can model out the whole scene in absurd detail (as is the case with the OP vid) and let your home
computer render the scene/video over 2 weeks. Then you plop the video in some kind of editing software, add some retardely simple filters to make it
look 'old timey' and add some retardely absurd 'old timey camera real clicking' sound effects, and viola, insta proof of Aliens. Of course, if you see
this kind of stuff all day every day (as I do), disbelief becomes a much more rigorous reaction to impose upon an individual.
