I'm a fan of Cyrodiil towns, but Skyrim really has so many great and interesting and fantastic places like Riverwood, Whiterun, Riften, etc etc. And the people and everything, before I thought a mostly snowy region would have okay towns but these are really natural feeling and like have their own personality and history. The usage of water in some of them is profoundly brilliant and masterful as well!

The people as well have great feeling, and I don't want to say spoilers, but the surprise in the Companions guild is soooooo awesome and it's really cool Bethesda adding that stuff and overall makes SKYRIM even better than all previous RPGs.
The combat and everything feels better too, and the HUD is a massive improvement as well. The 1st person and 3rd person animations are really well done and the sounds of course are incredible. It seems the dungeon designs were made with even more care and clever ways. And the questlines are even more interesting than I thought! There's still tons of things to do and see, but the main quest really is shocking and amazing!!!!!! The load times and screens are also very well done and it seems to go by fast! And there's just countless things great about SKYRIM and deserves GOTY.
They really surpassed themselves with this masterpiece!!!!!!!!!!!
