Whenever a new game comes out, obviously I want to play it at the best settings on my 4K monitor using the best hardware within reach. Soon after this need for excess is sated though, I'll consider the other end of the gaming spectrum—our $400 gaming PC that doesn't even have a discrete graphics card.
A good PC game will look awesome on the most extreme of hardware, but a great game will be able to scale the settings back enough to run on far more affordable hardware, while still essentially offering up the same gaming experience.
