about 13% of a population are left-handed
5-8% are color-blind (the radar, may be impossible to see friend or foe)

flexibility in control scheme is a good thing, almost a standar in games that have spatial 3d movment. (not full customization, but different layouts to choose from)

Most console owners have multiple games. standarized controlls or customization makes switching between games easier.
