Since you bring it up, Metacritic says hi. Killzone(75) and Knack (60) have worse scores than NSMBU (84), NintendoLand (77) & ZombiU (77). I'll give you Resogun (82).
But yeah, a million units in a day is pretty impressive. It's pretty embarrassing that Nintendo sat on it's laurels and Pikmin 3 was the biggest first party game to come out in the whole of 2013 so far. But let's not act like their big guns have already released. The battle is far from over. With Super Mario 3D World out starting this week, sales won't stand still over the holiday, you can bet on that.
Also I have a theory that Microsoft's PR fumbles earlier this year swayed a lot of Xbox customers over to Sony's side and pushed the numbers up higher than what are usual console launch numbers (400-600k). Not to mention the $100 price difference. Don't get me wrong, I think Xbox will sell out on the 22nd, I just think PS4 got a huge rush of support. Their PR departments were on point this year.
