Good comparison on the two trailers of GTA 6, in my opinion, if we put the HD era GTA (GTA 4, GTA 5 & GTA 6) for obvious reasons the 6 will graphically surpass the 2 previous games, in terms of gameplay also, I do not know if it will have as much life online as GTA 5, I guess so, but hey, it will be one of the best selling games of the generation and history, and in terms of narrative I do not think it will surpass GTA 4 and Niko Belic's background.
