I was raised on Dark Forces and Bond. When I first tried Halo, I used the Bond controls because I was used to it. At some point I decided to switch, and later played Half Life (PS2 version) and Halo with default controls. Point is, I can certainly sympathize with not being used to the controls. It really gets ingrained in you. I was playing like I was drunk for a VERY long time. Turning left instead of right, strafing into corners and not knowing how to get out, etc.
