Seems like you already made your choice
I still got two recommendations for you:
Try Bully and The Godfather if you are into GTA-style games.
Bully is by Rockstar Games and well you're playing a bully in a highschool. Not as childish as it sounds and actually great fun. If you always wanted to beat up Santa's dwarf-helpers that's the game for you as well 
The Godfather is a really brilliant adaption of the movie. You play as an un-known character and some of the mission are directly from the first movie. In the game you unite all the movie's characters which aren't really introduced to a single character.
