Hey, different strokes for different folks. I personally love Skyrim quite a bit. I also love Dragon Age quite a bit. Which one is better? Completely opinion.
I think both Bethesda and Bioware know their strengths. Bethesda is more of a search every nook and cranny, discover ancient secrets and role play to your hearts desire. Where Bioware is more story-driven, more-so about the characters than the world, type of game.
To put it simply, Bethesda makes games that are like kids in the forest, pretending they're knights, guarding forts and defeating trolls. Where Bioware games are really good books that we get to add a spec of our imagination to.
Anyway, that's my two cents. I don't think either type is dying though and I think both are good for RPGs.
