It's neither consumers nor other devs. Although other devs suing because Cyberpunk had too much hype would be pretty ridiculous.
It's investors suing due to the hit to the stock price. Which is also a pretty pathetic reason to sue since they probably released the game in it's current state since investors were complaining about delays in the first place. They made their bed, now they should lie in it.
Ah. Well then I stand corrected. Serves me right for not reading the article.
But, nah, that's actually a really legitimate lawsuit to the point that I'd be shocked it it isn't settled quickly. Withholding relevant information from shareholders is absolutely illegal. If the stockholders were being assholes that doesn't change things.
Has to be pointed out though that the investors are not exactly suing. Rather, CDPR the company itself is suing someone, presumably the board of directors.
