It has more implications as Diablo 4 and Overwatch 2 are probably out in the next year or two,and their predecessors sold over 60 million copies. So getting their foot in the door with Activision Blizzard is no small feat,as they already had a deal going with Warcraft 3: Reforged recently,and AMD GPUs actually had quite competitive performance(compared to Nvidia). In the past Blizzard titles tended to work much better on Nvidia GPUs,which kind of biased a lot of people to buy Nvidia GPUs for them. WoW itself has a frequent playerbase in the millions.It's what they need to do to actually sway more people to buy AMD products.
So this is part of the problem,even if reviews show AMD GPUs with competitive performance,the problem is if they lose in games which generally have larger playerbases and more important persistent ones. This is partly the reason I think Nvidia keeps outselling AMD in certain aspects too. Is it any fluke,that ATI beat Nvidia in games such as HL2,and that the following X800 series actually outsold Nvidia?? ATI had mediocre mindshare before that.Technically the X800 series was inferior to the 6800 series(lack of DX9 SM3.0 support).
