Endgame: Singularity is a game developed in python and released under GPL by Evil Mr Henry and Phil Bordeleon. In the game you play the role of an advanced AI whose aim is world conquest (the word Singularity was made famous by Vernor Vinge when he predicted that within the next couple of decades, humans would be successful in creating AI more intelligent than ourselves).
To play the same, you will need three things –
Ubuntu users can simply do a
sudo apt-get install singularity. But that will only install v 0.26a of the game.
Highly addictive! Hence highly recommended!
