I actually agree with shameless. I understand that mathematically they are the same but a 3/5 seems like a decent game to me, but i would be skeptical about picking up a 6/10 game.
They have the same denotation but different connotations.
Its like the words skinny and scrawny; they both mean a thin person but skinny would be a compliment but scrawny would be a put down. But of course this is just my opinion :P
