Why does it have to be a parody only of games? Parody in general is protected, as the games show.

Uhh… because that’s what we were talking about here….?

Where does it say it’s a parody of GTA…?

And that proves nothing but another person has your opinion, the only way to prove it would be a source from the developer, but that won’t exist since if they say it, they would be cease and desisted.
