Who will be the big loser and winner of the stacked October lineup?

[PAOerfulone]

Red Dead Redemption 2 is going to be the big winner in my view.
It's arguably the big game of this year and guaranteed to be a Game of the Year candidate. CoD and Battlefield will be a bit lower than they usually are because of this, but not enough to draw any attention.
Assassin's Creed will suffer the most.
