Haha, so true. I have been playing Picross regularly since they released Picross S, and am only at S4 yet, and they have reached S9, not counting the Sega Genesis and two other collaboration ones. I don’t think I am going to worry about running out Picross, as long as Jupiter is around.
BTW have you played Murder by numbers? It’s a “picross” + murder mystery story. It’s not by Jupiter, but I have heard good things about it. It’s also on sale right now, if you are interested.
