The use the WASD because it allows you to keep your hands shoulder width apart I imagine. Also allows your left hand to access more buttons within a smaller radius.
all good and well for anyone who's right-handed. but did anyone in the games-industry stop to think about left-handed people?
we're not that small a percentage you know.. Lately i constantly have to tinker with games' config files because some a-hole decided one predetermined key setting is good enough and there's no need for people to use anything different.. Well company folks, guess again! Left-handed people aren't comfortable with the same F#@$*%& keys you like so damned much! Nor are many right-handed people come to think of it.. What does it cost them to leave the damn key settings unlocked so everyone can use any keys they damn please? Sorry for the diatribe guys.. Just venting..
