Physics of the sim
Oh! The CSM story again. There wasn't any substantial work on that software since quite some years. It surely WAS good in 1996 but there have been some long cold winters since ... and other manufacturers did not use that time for a long sleep.
Again, the price difference reflects a good part of the usability difference. CSM is not playing major league at the moment and they surely have a stony way if they ever want to play that again.
