If you collect Switch retail games and really value uniformity, you might want to hold off on grabbing a boxed copy of Darksiders: Warmastered Edition for the time being. As you can see above, there are some game boxes out in the wild that have a black spine instead of the standard Switch red. THQ Nordic has confirmed that this is a printing error, but haven't talked about replacement plans, nor do they know how many copies are impacted.
