I played somewhere over 600hours on last gen, Xbox One X to be specific.
Did i have bugs? Yip ahd still do
Did it crash? Yip an still does but not to the extent it did
Disappointed? To a degree, in a few things that had zero to do with bugs or crashes or even how it performed on the One X but more about features, or lack of, in the game, story, CC etc etc basically things i tbh get disappointed at in all games to varying degrees because i have a opinion an think like everyone else about how X would've been awesome or Y would've been great but i got Z instead.
Every game, as i said, i have these thoughts/disappointments on while playing and ultimately it comes down to is the fun im having outweight the disappointment i feel at how a feature is, how a character/story is etc etc and well over 600 hours and about 20 characters speaks for itself in saying any disappointments i had were far overshadowed by the sheer fun and experience i had playing the game.
So for myself atleast, no releasing CP2077 on last gen was not a mistake, far from it, i loved my time in NC bugs, crashes and disappointments, all were buried as i hopped about either knocking ppl out with my fists, a bat or a dildo, shoot ppl up slow mo style with my pistols, AR or SMG or went toe to toe with my shotties not to mention my hackers, snipers, bladesmen, ninjas etc etc i had fun and i cant wait for the next gen patch, DLC and expansions to do it all again on Series X
