I searched for this topic and couldn't find it, i can't believe no one has opened a discussion on what a find a very interesting topic. 

In October 2018 a new Assassins Creed, Call of Duty Black Ops, Battlefield and Red Dead Redemption will release in the same order in consecutive weeks. One or probably even tho of those games will suffer in sales as a result. My initial guess would be that Assassins Creed would suffer the most and Red Dead will be the bigger winner. But if I look closer, Assassins Creed will benefit from being the first, Battlefield V's feedback from the community has been very mixed and Call of Duty will sell strong no matter what (which BTW is completely inexplicable, the game is basically the same every year and so fucking basic).

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.

how about Soul Calibur VI?? releases Oct 19 XD

Battlefield v the big loser and niche games since they don't have big audience 

Winners red dead redemption 2

Sales wise CoD will win easily, as it always does, probably followed by RDR2, just as its not annual and the hype has built for it.

How? By selling the most and the least copies/ make the most and least money.

I think Red Dead will take the victory. I think COD will be hit the hardest.

asscreed i feel will be the biggest loser out of all the titles, i feel BFV,COD,RDR2 will do better,with RDR2,if it doesnt get delayed,getting the biggest sales out of all the lsited

Honestly, all four will sell well but I do feel that Assassin's Creed Odyssey will sell the least and Red Dead will sell the most. COD and Battlefield will be close in terms of sales.

Hopefully Ass creed

Red Dead will sweep up.
