Looking for a new Linux game? Try Nero 2.0

Nathan Willis at linux.com has a detailed article on the new 2.0 version of Neuro-Evolving Robotic Operatives (NERO) -- "a unique game in which players train forces of autonomous bots, then pit those forces against each other in hands-off, artificial intelligence (AI)-only competitions."

NERO is actually a class project of the University of Texas at Austin's Computer Science department, part of ongoing research in machine learning. So, not only can you blow off steam by annihilating foes in competition, you can tell anyone who pooh-poohs your gaming obsession that you are furthering research in cutting-edge science. So there!
