V has established a new standard for switching characters. It certainly isn't a perfect system, but it's convinced me, a one-time-"no-multiple-characters-please" guy, that it's the future of GTA. to a degree. A lot of talk about the next title (apart from those wanting even more GTA Online, which I never play) centers around having two characters, a hero and a villain perhaps, who don't necessarily have to know each other, at least until the finale.
What about going to four characters? Including a woman perhaps? V features three archetypes which reflect the spectrum of GTA well; the organized man-with-a-plan (or so he hopes) Michael, the lunatic who just wants chaos Trevor, and the CJ-alike Franklin. CJ-alike in the sense of being able to do anything without it seeming too weird; wear baggy clothes, drive lowriders, play sports, all of that stuff SA fans miss. Including a woman would mean delving further into any of these archetypes or going in a completely different direction. How about a Madam (female pimp)? Let's say V had a woman in addition to its three protagonists; she'd get pimping missions, Trevor would get a drug-dealing game ALA Chinatown Wars, Franklin would get gang wars, and Michael would get empire building. Cutting out Franklin (everybody's least favourite character it seems- including mine) would retain the three character dynamic, but you'd lose all that fun gang related culture and clothing to dive into. Frankiln looks good in any clothes, whereas Trevor and Michael do not. A woman would obviously have more clothes than all the other characters combined.
TLDR: would being able to switch between four characters prove overwhelming for you?
