Video game development, especially for games of this calibur, take an insane amount of time, energy, people, and resources. The last thing Larian needs to do is listen to impatient complainers and try to rush out content.
What's the worst that could happen? It could just be free of bugs, no cut contents, and make everyone happy like Cyberpunk. I heard nothing but good thing when a game like Cyberpunk got rushed out.
Wrong paragon. Cyberpunk 2077 wasn't launched as Early Access but as full game.
Furthermore to add new content litteraly isn't a call for a rushed release of the full game, just that some new content would be appreciated, because to launch a game, even if in early access, currently means not only to make it a paid beta testing, that is supposed to have been done before the early access launch, but to be ready to have content for the players.
A players platform is not made only by those who have no problems to spend thousands of hours in search for bugs, glithcs, narrative incoherences, or to try new strategies to end the same quest lines, to understand the game to be able to make thre or two party runs, or to achieve the solo run, the platform its made from those players who like the background were conscious of the "early access", finished quickly the first act, and now would like to play again without the continuous sensation of deja vu.
To launch a game, even in early access, means to be open both to fix technical and narrative problems and to add new content (again: add new content doesn't mean to rush the full release, in the case of Early Access, just like for full releases doesn't mean to create a complete sequel).
