DreamWorks wins an award for its innovative use of Linux (c|net)

True.  but don't the vast majority of games and movies have little real enriching value to
human beings?  

Consider the open-source software freely available to linux users that is of lasting benefit:
tons of development tools, educational programs, scientific programs, graphics and multimedia
software.

and particularly, regarding games:

I suggest that most of the "latest" "hottest" new software that just busted onto the market
with much ado will generally receed from the scene at the same speed.

Most of the source code for those proprietary games gets lost after a few years when the
company goes out of business/bought/merged/whatever.  Most of those labors are generally lost
forever.  Whereas many of the open-source written ten years ago continue to influence new
open-source projects and the way cutting-edge proprietary games are designed today.
