I really love exploring in a rpg. If I ever can stop playing DKS I go futher on with Skyrim, I'm sure
... if not Divinity III or Dragon Commander is already out at the time DKS begin a little bit ... no, that can not be .... then ... in that case ... I'm not sure anymore
Skyrim is still very good, but DKS is outstanding !! And the Flames of Vengeance part is the icing on the cake
(or the "cream the la cream" or, in dutch : "de kers op de taart")
Not a big open world make a rpg BIG (like Skyrim and other TES games), also the music, the nice looking & funny NPC's and tons of humour (!!) ... and last but not least great quests !... I prefer quality above quantity ! Skyrim has many more content (and many many misc quests) than DKS, but since a rpg is a genre I like it's REplayability, a big open world isn't necessary for me. It's nice, but not THAT what make a RPG awesome !
