I dont understand why old ideas could not work with new visuals (like with Dragon Age). It has nothing to do with beeing old fashioned.
Actualy I am always as well glad to see games which decide to be sometimes different as well and not just in gameplay but also in the visuals. Why has every game to look similar? It hasnt. Diversity is the key for fun.
Some games should be party based. Others about a single character. Not every game has to be the same art or style.
Personaly I am someone who prevers party based games very much in the style of baldurs gate and rpgs in the style of fallout 1. But does it mean every kind of "RPG" has to be now that way? Should Diablo 3 play like Fallout 1 or Baldurs Gate now? Hell no! I like Diablo as the action game it is and should always be. But that on the other side means as well that games like Dragon Age (havnt played it) should not be similar to any "action" RPG (which Divinity 2 definetly is)
