Ah, gotcha'.
Yea, i personally hated the way GTA Online turned out and arguably many things that were standard option in previous GTA games didn't find their way in for some reason -- can't own multiple cars in GTA 5 for example, and CARS are in the game's name practically -- only to find their way in the Online version. Probably a means to draw people in.
That said, as pointed out many times before, here on the forums as well, Cyberpunk 2077 is more about the story, and when i say that i mean it in: how would owning X or Y make sense in that particular context, which we know precious little about at the moment.
Post-endgame content is something i would also like to see, BUT it highly depends on, well, the ending. The Witcher 3 tried to solve that by 'rolling back' the world at a point before the final mission, probably also why you didn't see the world having changed based on the events that unfolded and you helped shape. That and it would have been A LOT of work for something.. post-game, which wasn't the purpose of the game to begin with. Something like New Game + would be satisfactory for many i believe. That and the posibility to do some bounty hunting and what not, minor contracts, maybe some 'radiant quests'? Realistically no one should expect a Skyrim 2077.
