I've never gotten a Humble Monthly, because I dislike the blind surprise nature of them. I've got enough games that I know I want to play that I don't need to take a flyer on games I may want to play.
But with Xcom 2 as the feature game of this month? I may take a crack. $13 for Xcom 2 is probably good enough for me, even if I hate literally every single other game in the list.
