GTA 6: 10 Things Fans Most Want To See
5. Protagonists We Actually Care About
GTA protagonists are a unique beast. They can't be too likeable and righteous, lest all the ridiculous actions you'll be partaking in don't make any sense. On the other hand though, they can't be as completely vacuous and "Geddit? He's CRAY-ZEE" as Trevor, because then nothing on the story side lands either.
You can blame Bioshock for forcing the gaming populace to confront the notion of how characters think, alongside why we play them in a certain way (hence Niko Bellic's motivations to live peacefully making no sense if you take a rocket launcher to a crowded room), but I think Rockstar nailed it back with Tommy Vercetti, CJ or Vice City Stories' Vic Vance.
All three never took themselves too seriously, could easily walk the line between free-wheeling anarchism and story-related motivations, and were just plain fun to embody. That's one thing that Niko Bellic and GTA V's trio of characters lacked; fun.
A recovering gangster-in-therapy, a murderous cannibal and a gangbanger with delusions of grandeur do not enjoyable protagonists make. By the close of GTA V, each main character was in the exact same place as before, save for Franklin getting a house upgrade.
Let's have someone who actually has a defined arc and sense of progression throughout - similar to how CJ went from the grimy suburbs to those high-rollin, Las Venturas casinos.
