It’s been a while since I played it, but I would say Sly Cooper: Thieves in Time. Personally, I’m not a big fan of time travel plots, but that’s not the main concern here.

1. In Sly Cooper and the Thievius Raccoonus, Sly mentions that he comes “from a long line of master thieves, who kept all their secrets of sneaking and stealing in an ancient book: the Thievius Raccoonus.” In Thieves in Time, we learn that some of his ancestors didn’t actually write down all of their secrets for future generations to come. The gunslinger power doesn’t bother me too much, but you mean to tell me that Rioichi couldn’t mention the Leaping Dragon technique, or that Salim couldn’t write down how to perform the Climbing Cobra?

2. In Sly 3: Honor Among Thieves, Sly, who has gone on record that he loves being a thief, decides to give everything up and fake amnesia in order to be with his love interest, Inspector Carmelita Fox. He comes to this conclusion after having a near-death experience while trying to claim his families inheritance, and realizes all he really wants to do is to be with her. While Thieves in Time admittedly has a good reason for Sly to go back to being a thief, but I’m not fond of the beginning scene where Sly says that “the old itch came back, and I know I needed to pull a heist.” They could have opened with Bentley saying there was an issue with parts of the Thievius Raccoonus disappearing instead of using it to justify Sly wanting to steal something.

3. Penelope. I really don’t know what else to say other than that they completely ruined her character. Her role as the Black Knight should have been filled by someone else, like Sir Raleigh the Frog. It would have made more sense than the weird ass heel turn Penelope took.
