for me is the fact that it is brand new, so I will be playing it for at least a year straight before going back to Oblivion or Morrowind...which will make O and M seem like new again.

Go back..? Wha ?

i will probably stay on skyrim, not go back.

I just get tired of playing the same game forever...years at a time for a new one, yes, but then I play the old ones too.
