Rockstar said GTA 6 costs $79.99 across PlayStation 5 and Xbox Series X and S, confirming a $10 jump from the standard $70 we’ve seen this generation. The Ultimate Edition, meanwhile, is $20 more, priced $99.99.
GTA 6 physical copies do not include a disc, Rockstar has confirmed. They’re just a code in a box



Website details the game actually blocks off stuff if you don’t buy the most expensive version
They are insane if they do that.
Blocking stuff off means, what though? Any game with 2 editions and a difference in content can be seen as glass half full or half empty: the higher edition “adds content to the lower edition”, or the lower edition “blocks content from the higher edition.” Usually the missing content is vehicles, guns, skins, costumes, etc.
But if they’re blocking parts of the map, or he story, then that’s a whole different beast.
It’s guns, cars, and cosmetics, of which there will be plenty in $80 version. The one part that’s hard to evaluate is that the larger edition has more “businesses”. An educated guess is that it’s the real estate minigame from Vice City, and there are a few properties that are only in the more expensive edition, but that’s only a guess. It doesn’t sound like whole storylines are locked off.
Found IGN’s list of things and that sounds about right.
