For me.
It feels like an mmo but doesnt have a grind to it that i usually notice after a couple hours.
Its feels like elder scrolls. It is captured perfect.
PVP
No restrictions. Meaning i can pick up any weapon or decide to craft without feeling like im behind because i have not been doing it.
Quests. Plan and simple they are fun. Sometimes so much that i hate to see certain quest lines end.
The perfect way that i can explain this game is its like if beth released a game inbetween oblivion and skyrim. A little lf both to make something awesome that you can play with friends.
Those are mine. I say they pulled it off and went above and beyond what i thought would be a mess.
