Fable 2 Dev Diary 2: One Button Combat quote from Joss Moore
"For Fable 1, we had loads of different ideas about how we wanted to move forward with the combat. And we always would come up with a new thing and there'd always be the standard problem of how we work this into the controls. It was so limiting thinking "Well, we've run out of buttons for that. How will the player actually make this happen?" By stripping back to just using one button it seems the sky is the limit all of a sudden. Anything we can think of based on the context that it's appropriate, we can do. Just with a single button press."
Joss Moore, Lionhead.
