3Mute Protagonist
Source:Geek.com
If you want a successful GTA, you need a character whose personality is unknown. For instance, in GTA IV, Niko was always talking about how the life of crime was not what he wanted and yet, his actions spoke a different story. Meanwhile, Trevor in GTA V was a psychopath from time to time, and we doubt a lot of people like to control such a character. We need the protagonists who just nods along, a Yes-Man whose personality is hidden.
