So far I've played for about 20 hours Skyrim and it's amazing world

!
The world feels indeed alive !
Also for me Skyrim is in many ways better than Oblivion ... and as I espected, but even more amazing THAN I espected(!), I love it to walk in the mountains by day and by night ... it's a fantastic feeling to look around standing on a high mountain path or whatever you like ...
.. you really must TRY this:
just standing on such a nice place for some time and doing nothing but just standing there ...
after awhile you will see Bethesda make some sort of "screensaver" : the whole world around your hero starts to turn around, 360 degrees & further on around and around !! It's freaking awesome
