Genshin Impact sure had some top-rank music team and bunches of money to co-op with London Philharmonic Orchestra, and we players are glad to see this. The medieval style music the game currently contain is refreshing and peaceful, but somehow too gentle. I wonder if HOYO-MIX would use their experience of creating modern-style-music in Honkai 3rd into Genshin Impact.
I'm gonna use an old example:
Shin Megami Tensei: Devil Survivor is a SLG game on NDS released by ATLUS in 2009, as an near-post-demon-apocalypse game its music combines rock and classic style. The song 'Demon of Darkness' here integrated elec-guitar and pipe organ and gives me a badass feeling. I believe Genshin can use some musical instrument combination to express the different scenery and atmosphere of Teyvat.
