The question "what game is the graphics king?" is similar to "what's the fastest car?", not "what's the best car?". The second question involves too many variables not related to the speed of a car.
Graphics King =/= Art Direction King
- I find Super Meat Boy artistically pleasing. It's the most beautiful game I've ever played, but it's not the Graphics King.
- Crysis 2 on console is the console graphics king, but it's not the Graphics King. Crysis 1 with mods is superior.
