This may sound like an unusual question, but I was wondering if there are any legal implications in using satire within a game? (I dare say the same would apply across all forms of media but as this is a game development community...) I'm sure that naming other peoples IP within a game - without permission - is asking for trouble, but what if the reference is a little more subtle, but can still be identified by the player?

Parody: Fair Use or Copyright Infringement

Short version: It's probably fine.
