That's not an excuse. I assume you've heard of Q&A or an actual test platform staffed separately from the devs. For this game to release when it did and in the condition that it did was insane, irresponsible, whatever you want to call it. Their excuse was BS, they knew 100 percent how F'd up the game was, especially for last gen consoles, BUT RELEASED IT ANYWAY!!!! You can add arrogance and greed to the reason why it happened as well.I am not a developer, programmist, or anything like that.
But think about it logically. With the Witcher 3, CDPR had lots of experience. The Witcher 1 and 2 are games with lots of flaws (especially 2, with its clunky inventory, broken minimap etc.) but they provided them experience for the Witcher 3. They knew (more or less) what to do and what not to do, because all the Witcher games share the same setting: a medieval fantasy with lots of combat, intense story, and lore.
This is not the case with Cyberpunk 2077. The game is their first title set in a futuristic setting with guns, cars, skyscrapers. They even changed the camera perspective.
They simply didn't have enough experience with that kind of game, and they failed.
My Xbox One X is playing the game better since 1.11 hit, BUT, we should never have gotten to this point in the first place.
They certainly have plenty of experience to dev games and doesn't matter what type of game. This was another RPG, different setting, different characters. They also lied about taking 7-8 years to develop it, the pre-release trailers were BS and we're where we are now. I just hope CDPR management is thoroughly ashamed at what they've done.
