Ah.. finally, someone who gets me. ^
And Official General, you get it too. But you think Miami/Vice would still be different enough. I can dig that too.
That's really the crux of it for me. Like Jab said, it would feel like going from one sunny beachy city to another that will offer not much of a change of a color palette, unlike the difference going from III to VC.
But I get that a new Vice City hasn't been done in HD too and people still want that. In fairness, I would love to see that too but a HD version of an all ready covered city such as GTA 6: Vice City is like an upgrade of an iPhone for me. A brand new location and a possible change in time period is like a new phone and a different brand: Just a whole new experience.
