I wrote a 4 page dissertation on why I felt CrowBCat isn't wrong and how handicapped some of his points are, but I felt it'd be wasted on an OP dumb enough to post this stuffty video to the forums.
GTA IV is far, far worse in quality than GTA V, and we're not even talking about the GTA IV PC Port, objectively one of the worst ports in the history of video gaming. If I want to play a game that feels floaty, that has terrible police AI, where cars handle like boats and won't auto-flip and which looks like stuff thanks to the dulled colours, I will play GTA IV and remind myself of all the hours of frustration and anger that game gave me.
Besides, let's be honest, the GTA V story characters are WAY more entertaining than Niko and his troop, without a doubt.
