Surely not the only, but maybe the most famous, use of the prefix "uber" was by Hitler in his writings and the Nazi party in the word "ubermensch". It literally means over-men but is more correctly translated as supermen. It was used in refering to the supposed superiority of the Aryan race over all others and used to justify horrible acts by the same.
Fortunately "uber" here seems to have a more benign connotation meaning a super or ultimate strategy. It does come out of the tradition in Role-playing Games of "munchkinism", or the maxing of stats and skills to make the game as easy as possible and ignoring any role-playing in the process. Mind you I have given in to "munchkinism" myself from time to time, and found it a useful method of play when testing the limits of AI. Fortunately the games we play lend themselves to many styles of playing. There is no need to look down at those who play differently than us.
Please excuse me if I bored you, I started out explaining some German and ended up preaching.
