What I don't understand is... if you have delivered a demo prior to released date, have let people try the game why suddenly be affraid of reviews?
People that are skeptical about the game and have played the demo aren't going to ignore this, and people that will buy the game no matter what reviews won't matter for them. Even so, you have to be pretty confident the ones you gave reviews code will actually do a decent reviews about your game.,
I recall something related happened when CP2077 launched, and yea many reviewers gave the game 9-10 but there people hadn't played the game a bit, now you have a demo available (at least for PS5), what is the point?
