The visual improvement is probably the first thing that caught my attention too. Rockstar seems to be putting an insane amount of detail into the characters, environments and even the little things happening around the city. In RDR 2, they already showed what they can do with the graphic. I'm excited for the game, though I'm not sure in how many years I'll be able to play it cause I had to wait for more than years to play GTA V, lol.
