Love interests will never get their own game. Because their motivations and goals or personality are saddled to the MC. Knuckles doesn't need Sonic to thrive, you can easily bullshit some more Echidna lore or Master Emerald heist shenanigans. Tails can do his own thing too. But Amy? Her goal is to catch Sonic and convince him to marry her. Shes somehow a 13 year old who can summon magic mallets and smash robots to bits in fits of anger, but they don't do much else with her past that.

Are there even any modern prolific videogame music composers now? We don't hear about anyone new or upcoming despite them wasting billions of dollars of taxpayers money to make them, which would naturally include the music.
