Where? Is it still the stellar team that wrote the other witchers or is it now being done in America in the new offices of CDPR? Because the US Dev track record the last few years has been shit (outside of PlayStation studios single player games). Here's hoping Avowed bucks the trend. As for the witcher, I hope production takes place this side of the pond, otherwise we will end up with a witcher 4 with the blandest, inoffensive and messageless writing in the history of the franchise.
I can already imagine a witcher where the main character uses the power of friendship and positivity to hunt draugrs...
The project is focused in Poland, but for a project of this scale it is common (and reasonable) to distribute the workload. So I'm sure there will be parts of it being done in the US.
Where are you getting this idea that American game devs all make the safest most harmless games possible?
GTA is an American-made game franchise and it's one of the most violent and insulting mainstream titles ever, made by Rockstar, an American company.
On the other side, Tt Games, which makes all the Lego titles of the past 20 years, is a UK-based dev studio. They're some of the safest, least offensive games ever made.
