Graphically we take a slap in comparison with the previous version of the game.
I think the level of play was also evaluated richer, I can not give a definitive answer because this is still work in progress ...
Purists will say "bah, there 'Morrowind Upgrade' a level that challenges the old opus ...
Anyway I think it's like with the Dune series, if we begin with one must read the whole series ...
Well, even the long evenings in perspectives ...
