Mainstream anime such as DB,DBZ,Sailor Moon, Naruto, Bleach, SAO etc. seem to appeal to the normies and Chads and even some foids, (mainly sailor moon, cardcaptors, inuyasha)
Mainstream games such as Super Mario,Pokemon,Legend of Zelda,Megaman,Sonic The Hedgehog etc. appeals to normies and foids as well.
But niche anime such as Haganai,K-On!, A Certain Scientific Railgun,Lucky Star, Haruhi etc. seems to appeal mainly to incels, since most normies don't like these kinds of anime due to the abundance of anime girls in them, and most people who like them are always usually autistic subhuman men.
Same applies to niche games such as Hyperdimension Neptunia, Akiba's Trip, Persona, Blazblue,Guilty Gear,Arcana Heart etc. They appeal to mainly incels(weebcels/ricels at least)
Considering Japan has a very large number of incels, I guess it's no surprise that these are made for them, and these niche copes just so happen to appeal to a number of incels outside of Japan as well.
So it's hard to say really.
