Remember that simple circle-and-a-stick game our fathers used to play when they were kids? You took a metal wheel frame from a bicycle and roll it down the road, trying to keep it steady by using a stick. Try and compare that game to – let’s say – Glest or Starcraft. Now hold that image in your head for a second and imagine trying to stabilize that iron circle with nothing but a scarf. You’d have to pull on both ends of the scarf and try to somehow keep the balance of the rolling circle. A stick would be much more handy, but where’s the fun in that?
