This series is the fine-dining of video games. Sound, graphics, lighting, physics, detail- It's all immaculate. There's no gimmicky gameplay features for the sake of making it more "fun". (Even other racing sims are guilty of this.)
Everything put into these games has to be perfect. From the individual sound of each engine to the pristine detail of the key lock on each door handle. I mean this in the best way possible, but you quite literally have to be (an extremely high-functioning) autist to make a series like this.
I cant even fathom that there are people like Yamauchi rubbing shoulders with Nomura in the same city. Polyphonyare just so far removed from every other Japanese developer. They're the only ones that can truly grasp subtlety, elegance, and class in the video game industry. Yas Forums could never understand. Your brains are just too primitive, I'm afraid. Now if you excuse me, I must attend to some bossa nova dancing now.
