Yeah I received both Mario and Zelda yesterday since I preordered them, and I can tell you they are both absolutely amazing! Especially Zelda is really great, it seems they changed the mechanics quite a bit but that is great, it doesn't feel like the same game we played ten years ago already.
The best thing is, I just finished Xenoblade Chronicles yesterday after putting 80 hours into it, so the two games came exactly in the right moment
