11. Fight Club
Given the first rule of fight club, we shouldnt really be talking about this, but the most recent entry in the series, The Ballad Of Gay Tony, added a distracting method of utilising the games combat system by providing an arena where players can engage in fisticuffs with NPCs, wagering on the outcome. GTA5 could build upon this by integrating the multiple fighting styles featured in San Andreas, allowing players to fight NPCs, or even each other online, in Tekken fashion.
