I agree that Xenoblade does not come across as a very polished game. I never finished the game, but would like to go back and do so sometime; I think I posted about my gripes with it's graphics back when it first came out.

As for DQXI, my vote is yes. In fact, DQXI is among my favorite games of all time. It was so recently that I finished my playthrough on PS4, so I don't know that the new additions on Switch will be enough to make me play it again just yet, but down the road, for sure.
