Another detail to consider is that these gift cards can be used in the official Microsoft store. That means that they can be used to purchase Microsoft hardware in addition to games, including the Xbox Series X. New consoles are sold out, but the gift card money can be used should they restock down the line.
Gift cards like this make for excellent purchases either as gifts or for fans buying for themselves. Gift card currency is just currency in the end, and since most video game players are likely planning to make a game purchase in the relatively near future, this is basically front-loading a 10 percent discount on that game purchase.
