IDK, GTA V bordered on "bad" for me and ended up just being "meh." It got a lot of praise, so I kept going back to it thinking I missed something, and ended up forcing myself to finish it. It was pretty bland story- and character-wise start to finish, side content was mediocre, and the gameplay was fun but not particularly unique (felt like SA gameplay with better graphics).

If GTA VI is just GTA V with better graphics and not much else, I'll probably pass. It'll probably be successful regardless though for the same reason people keep buying Bethesda games. I want an interesting story where I care about the protagonists (def the case in IV and SA), interesting twists and turns, and something new gameplay-wise (e.g. I loved the gang warfare in SA and more realistic driving in IV). Switching between characters isn't "new gameplay" imo, especially if I don't care much about any of them.
