It should not surprise anyone that otakus who got into Hoyo through HSR and ZZZ are more brilliant than those who joined via Genshit alone.
Fans from other communities (Type-Moon, Yostar, DMM, and Cygames) may have an advantage in engaging with HSR’s intricate plot and gameplay. This could explain why some JP fan artists from these communities prefer creating art for HSR and ZZZ over Genshit instead.
