Tomcat I am of the opinion that there is a difference in requirements between users/players and developers/creators. For example, it is recommended to develop the game on a computer level higher than the recommended for maximum quality of this game. Well, that's how I was taught…
I would argue for the opposite, you define the minimum spec for the widest audience you want to possibly capture and develop against that minimum spec. You should still test higher end systems including monitors as well, especially now that we have ultra wides and super ultra wides and whatnot.
