GTA V feels...well...like a casual game and for mainstream gamers.
It's weird because the series has been insanely popular for well over a decade, but up until GTA V they seemed to be confident and content doing things their own way. Them being the ones that took risks and set the bar for games across genres. This entry however seems to have been influenced by it's competitors. Sadly I really think they lost their balls and tried to accommodate those that found other unmentioned urban open world games more accessible.
