How do I rename installed pkgs?

Is there a way to rename some of the games I have installed? I'd like all the names to be consistent but you get some games that are listed in all caps, some lower case, then there's some that just need renaming like how both games from the Bioshock Collection are simply called "Bioshock: The Collection" with the icons being the only way of differentiating them.
Can I not rename these?
