This and GTA 5 are probably my two favorite games. I am torn between which one is better. I love the story and city in 4 better, but the graphics and story in 5 are pretty amazing too.
You cannot go wrong with either games. I wish the would bring back Niko for GTA 6. There are few must play games and both of these are must play.
My only complaints. The games are two short. I could play this game for half a year and not get bored.
