Stuff can always be improved, always. Improvements to stuff won't ever cease until it reaches perfect (which, won't happen). Thus, 100 out of 100 is the ideal, doesn't mean it'll ever happen. But if it does, and there's finally a 100 out of 100 game, bam, perfect game. If 100 out of 100 is 'less than perfect', what is a perfect game on the scale then? 101 out of 100?
