Its funny about that statement where people talked about Crunch time and CDPR flaked out. They most definitely crunched and it definitely wasn't enough.
As far as I can tell, the blame lies primarily with management and the developer leads: they got it wrong when trying to assess the amount of work required to finish the game and, while the Coronavirus epidemic is a legitimate mitigating factor, it only goes so far.
CDPR put themselves in a losing bind with their second delay, when they shifted the release date from April to September 2020, rather than biting the bullet and pushing the game into 2021. Gamers would've bitched (myself included, I admit) and investors would've been rattled, but they had good business credentials and could've laid blame on the pandemic. Instead, from September 2020 they went into the deathly spiral of smaller delays and "just three microissues left" in a mad dash to make the Christmas holidays, from which they could not then pop out and say "actually, see you next year."
I say this because I believe stockholders would've been more amenable to fewer but longer delays, given the exceptional circumstances (Coronavirus), simply because that would maintain confidence that management still has a reasonably clear picture of what's going on, rather than what happened, where CDPR looked like they were playing a desperate game of whack-a-mole in Microsoft Project.
That said, I don't know what their financials looked like. I
believe they could've kept going for another couple of months relative to what ended up being the release date, given the hype and their successful GOG and Witcher properties, but I have no idea what sort of pressure they might've faced from creditors through 2020 after "eight years" of working on the damned thing. So maybe I'm talking shit and Cyberpunk's fate really was sealed when Covid-19 torpedoed Europe last spring.
As for "more crunch", instituting a formal 6-day week much earlier might've helped
some, but I don't know whether it would've been enough. The thing with mandatory overtime is that, aside from labour law and cost limitations, the longer it goes it also becomes a case of diminishing returns as developer morale drops. I guess we'll get a better picture of how much more work was really needed once Cyberpunk makes it back to the PS store.
