I feel this sets a bad precedent. If putting out a buggy game results in a class action lawsuit, Bethesda will cease to exist. lol Seriously though, it's a slippery slope. So, if a bunch of people watched an anticipated movie and hated it, can they sue? How about music or books?
It is not about buggy product but it is about misrepresentation in order to obtain financial benefits.
How come you've asked ... Look at sequence of events below
1. After Cyberpunk2077 released, CDPR announce that Cyberpunk 2077 made up all its investment costs on its release.
2. As result of this investment most (maybe all) of their investor hold their shares, hoping the value will increased because of this "good" news.
3. After sometimes some customers complain because this game has its bugs, and media blow this case up.
4. This cause some companies, even CD Projekt Red changed their refund policies to accommodate the game's frustrated owners. These refunds may
reversed the previous announcement that Cyberpunk 2077 made up all its investment costs on its release.
5. Some investors see that, in foreseeable future, will make shares value plummet and make them loose money.
6. Hence the class action suit, because the investor felt that CDPR do misrepresentation their finacial conditionin order to obtain financial benefits
