Ratchet and Clak is a 14-year old franchise with 15 games, a movie, a comic and a manga!
Had no idea there was a movie until last week. Probably would never have known if I didn't work at Wal-Mart where there is a single small advertising banner for it next to the PS4 games, where the game-of-the-movie was already out before the actual movie was. Said game-of-the-movie has sold maybe a handful of copies since we got it in, at least during days I've been at work. Compared to, say, Call of Duty: Black Ops 3 or Star Wars Battlefront or Dark Souls 3 (that one sold out
twice so far) it's not selling well at all.
Meanwhile, when Resurrection F came out on DVD a while back, they had a giant cardboard display of Battle of Gods/Resurrection F DVDs right out in the front of the electronics department and from what I remember quite a few of them sold, and pretty quickly too -- the display was jam-packed full of DVDs when it first showed up, and after a little while only one side (out of 4) had any DVDs left in it at all. We still get a copy or two each of Battle of Gods and Resurrection F every other week or so, and there's always an empty slot on the racks to put them in -- they're never overstock that needs to get sent back, unlike a lot of movies. People are definitely buying them.
And this is in a fairly small area that seems to have a lot of people who own Playstations; we never even got the most recent DBZ games in stock (I was looking for the 3DS one, too...), so I'm guessing the DBZ games haven't sold well around here in the past. Even here, a new DBZ movie sold amazingly well.
Yeah, Dragonball is much, much, much,
much more popular as a franchise than Ratchet & Clank.
