I wouldn’t say I’m a fan of them, but I don’t mind them. If there’s a game from that list that I really, really want to keep playing, I can just buy that game. In the mean time, I got to enjoy all the other games that were fun for just a short time.
I definitely prefer XB Game Pass instead, though, where the whole catalog is available no matter when you started and whether or not you clicked a button in time.
