I'm a patient RPG player, so I like RPG's that don't hold your hand ! RPG's where I must use my brains ... And I read ALL books/notes, etc in each RPG ... but honestly, I love reading!
And patiently search/explore the world from A to Z to find secrets and hidden loot etc ! Love that !
Yet in all the Divnity games and Risen exploring the world from A to Z rewarded the player's patient. I think Oblivion too, but can't still say it for sure.
I never played DAO, so I can't compare that game with other RPG's.
Maybe the voice acting in TW II is less interesting then in the DKS and so on, but I'm sure TW II has also great things to have fun with !
