I'd like to note that in the previews, they said that you cannot succeed without the companions. Each of them has a reason why they need to be part of your party, why they need to help you stop the end of the world. I am really getting tired of this trend in CRPGs, where the party or the companions are as important or even more important than the PC. The PC should be the protagonist and the driving force of the story and the game, companions should not take such a prominent position. BG3 also had this issue, where the companions felt like they were more central to the story than your PC is. Granted, that's a Larian issue in general, but it's disappointing to see other studios starting to follow suit, although you could argue it was already starting to happen even before the Larian games.
