dark souls would be like complicated actual orchestra music
tf2 would be like the old electro/drum and bass that eventually turned into one dimensional shitty trap/pop music (overwatch)
battle royale games would be the new wave of talentless soundcloud rappers that are just stealing and mixing a bunch of older shit that they dont have the depth to understand even remotely
minecraft would be approaching nirvana/other indie electro that didnt have many defined rules for the genre or similarities between songs, and quickly got associated with 10 year olds and died
MOBAs would be kpop no doubt
call of duty/halo/battlefield would be disney-channel country/pop that was hyper popular and gained an audience of younger children during the 2000's and then was never relevant again, leaving a large population ashamed of their interests and completely alienated from all other genres
