maybe Nasuverse has better world bulding but that doen't mean Masada isn't capable of creating a better world then Nasuverse. let's say why
Nasuverse had multiple Visual Novels, multiple PSP Games, FGO, Multiple animes, mangas and etc and they are about creating more animes and mangas too + their current ongoing series such as Strange Fake, FGO and etc
they had pleeeenty more time for making Nasuverse bigger when Masadaverse had only 4 visual novels (Dies Irae AA, Dies Irae IWKB, Paradise Lost and KKK) + one shitty anime and then light got dissolved. how tf Masada was supposed to creating a better and bigger world? that's like saying Berserk is supposed to having comparable world bulding with DC or Marvel comics.
and not to mention Light was a freaking shitty studio and not only never tried to translating anything (it got freaking years till they translated 2 novels of franchise) or even Advertising Masadaverse but they created worst anime in existence for Masadaverse too and that shitty anime pretty much harmed Masadaverse and created a globally bad perspective about it.
at same time most of Nasuverse materials got translated, they created plenty animes and mangas (anime and manga is pretty good for Advertising and is far more globally known, famous and popular than a visual novel too) by one of the best studios in existence called ufotable. now you can see why Nasuverse is more popular or bigger? not to mention idea for using Historical Figures was a more popular idea in general too (which i dislike cuz i never cared about history or historical figures that much)
and we can stop talking about that crazy nazis thing please? that's subjective as hell and pretty annoying for me. Willhelm was one of the best and most different characters for me. someone crazy as hell, who had his sister as his mother and raped and killed her, then slaughtered his own father, turned a serail killer, then a nazi and not even Claudia's love and sacrificing affected him + his excellent voice actor and fights were pretty ineterest to me. also Willhelm vs Shirou in Marie Route was easily best fight in "my life" and i'm someone who got used to watching over 200 animes, played coutnless games, read multiple mangas, watched countless movies yet Willhelm vs Shirou was best for me and yeah i perfer Masadaverse crazy nazis idea over Nasuverse historical figures (i have watched FSN, UBW and i have multiple fate experts as my friends too so i'm not dumb when it comes to Fate too). so please give a end to this nonsensical annoying comparison between Masadaverse and Nasuverse.
and you told us Masadaverse' romance is dogshit? i don't give a shit about Romance so i don't care. i always hated Romance and every Romance anime such as SOA in general. interesting and overpowered fights and characters for me >>>>>>>>>>>> Romance. i was a Dragon Ball fan after all and Dragon Ball is globally known for overpowered shit too. so you can see now those arguments are pure subjective and nothing more than annoying. although frankly i don't think Masadaverse's romance is that bad.
