You are forced to buy the dlc with it. All up, $30. If there was a $10 upgrade for the base game, this thread wouldn’t exist.
But that's because there is no "base" PS5 version, so if you want a PS5 version, you need to buy the director's cut expansion first.
It's not really different than the Control Ultimate edition in this regard, only that you can actually upgrade your base version, at least.
It's shitty, it could have been handled differently, but it's not the end of the world, considering that we will have 2 or 3 other games being possibly affected by this, max.
