I agree with McShagger, all video games should be absolutely 100% realistic and true-to-life all the time.
In COD if you shoot an enemy in the torso a few times you should have to wait a certain amount of time before he dies, somewhere between 2 minutes, 3 hours, and not at all, depending on where exactly you shot him.
In Halo, Master Chief should be unable to walk because of how heavy his armor is, also there should be no aliens
Metroid shouldn't exist
When Mario jumps into bricks above him, they shouldn't break, he should die because hitting your head that hard would kill you
There shouldn't be any dragons or magic in Skyrim
Tetris shouldn't exist
