So in your weird definition Elden Ring is a WRPG and Dark Souls a JRPG?The entire narrative and lore of Elden Ring was written by a Western dude! George R. R. Martin. It's basically a Game of Thrones with High-Fantasy as setting. Again Elden Ring is not a JRPG. It's mimicing an WRPG which was developed by a Japanese studio.
BTW George R. R. Martin only write the worldbuilding.. everything else was Hidetaka Miyazaki.
