There are plus and minus if you compare it with Skyrim. I can point it out since I have played like 500hrs or more of skyrim way back.
Plus:
--Companions interaction is deep. Sometimes hilarious, sometimes dark humor and sometime simple caring thoughts.
--Tactical Combat still is fun in RPG genre. This game proves it very well when you are put against a challenging enemy.
--Fight against Dragons. A good dragon fight will take decision every 3-5 secs. The battle might go for long durations. For eg. my last dragon fight in which the dragon was 1 level more than my team (except me), it took us around 25 mins to finish him off.
--Crafting, though in the beginning may looks hard and confusing, once mastered, you can feel the power you crafted.
--Huge skill pool to play with. Especially when you can control every companion. Powerful spells indeed look powerful. One can create combos with the help of certain skills used in particular sequence
Minus:
--No other storage space apart from your inventory which is 60. But its still more than enough if one is not a hoarder. Ingredients, crafting materials dont take space.
--Those shouts in Skyrim will be something one might miss.
--Open world like Skyrim isnt here. But there are 2 main regions with many sub regions. And dont mind the absence of open world, the sub regions are actually pretty huge.
--Some times the AI acts stupid. For eg, the party members will be near the human enemies and enemies wont do anything just because the current character the one you are controlling at the moment) is in invisibility mode. But same goes for Skyrim as well. For eg with 100 lvl pickpocket and Sneak I was able to take off the women's clothes in broad day light without any hostility
--Long loading times but that just may be my processor getting old.
You will get different opinion from other people here as well. These was my experience so far in the game.
