Garfield MMO: You play as Garfield's past livees in Heaven, main enemy is Blinky and his mooks are Nermals, you get living Pookies as pets, you can ride Odies into battle, Jon isn't in the game
After my mom died and noticing famous Animals dying, my hyper empathy went further beyond, each time I see a cute cat or dog, I think how depressed the owner will be when they're gone, it even applies to my own pets, sigh
Batman gets his own game series and hogs crossovers but they don't even attempt to touch those other heroes out of crossovers, I don't think Wonder Woman has even got a standalone game at all
But yes, this is something that is a pretty surprising casting given how most of the characters are properly cast, with Donald being Fred (obviously appropriate given that Donald and Scrooge are already nephew and uncle), Willie the Giant as the Ghost of Christmas Present (this ghost is normally depicted as a giant) and Mickey Mouse as Bob Cratchit (since Mickey is typically depicted as the cheerful underdog).
The only two reasons I can conceive Goofy being Marley are two things: one, to put Goofy as an important character since Goofy is one of Disney's best characters, and two, for the physical comedy shenanigans from Marley's chains. Goofy is otherwise too good-natured to be depicted as Marley. Horace MIGHT be a better fit but as it stands, Goofy had to fit somewhere. To a lesser extent, Pete being the Ghost of Christmas Yet to Come is an odd choice, but I liked it a bit better for the unexpected choice.
Thank you for reading.
