How about instead of GTA its Saints Row: Vegas. Its perfect, the storyline could be Dex fled to Vegas thinking "Boss" wouldn't find him there, then he goes there and takes out gangs there and takes control of the casinos and everything to expand the Saints. Won't happen, but would be nice.
i wish R* would do the next game in Vegas, no dissespect to NY people, but Vegas is WAY more fun, i wanna own a casino, as phat house like what his face had in oceans 13, and a few hundred italian sports cars baby, play black jack, get into a texas hold-em tourny, oh wait TIV has that, RELEASE THIS GAME PLEASE!!!!! NOW!!!!!!
