Heretic of The Seventh Circle
So, first, not all media is going to influence a fantasy game. I’m an elder Millennial, I remember the shooter called Heretic.Why only the youngest millennials? Many of them grew up watching Pokemon, Dragon Ball Z, Neon Genesis Evangelion, Yu Yu Hakusho, Inuyasha, etc. Often, when they grew up, they added more adult things like Akira and Ghost in the Shell to the list. Millennials are the "Adult Swim"/"Toonami" generation.
While I wouldn't consider anime to be exclusively dominant, it's going to be way, way up there. You'd also have influences from major video games of the period where they were growing up: shooters (DOOM, Unreal, TF, HL), action-adventure (Zelda, Dragon Quest), platformer (Mario, Portal), "Metroidvania" (exactly what it says on the tin), single-player RPGs (Mario again, Golden Sun, Final Fantasy, Planescape: Torment, Deus Ex), and last but not least, early-generation MMOs (UO, EQ, WoW, SWG, FFXI, etc.)
Hell, I'd even argue that much more recent things like Minecraft should be thrown in there as well, but those are new enough that they might not be considered "formative" for even young millennials (who were generally adults when Minecraft finally, officially launched.)
beyond that, I think that it’s likely that older millenials would be open to anime influence, but IME my Gen takes more old and over the top anime a lot less seriously than newer or more serious anime. Probably in part because of how awful a lot of early dubs were.
But there isn’t any weird baggage of that type with something like The Last Unicorn. I’ve never seen anyone make excuses for it.
But yeah sure we can add fantasy anime, no worries.
