... because they stubbornly try to convert a 5 star scale in to a percentage for aggregation.
 
It is okay to say "who cares about metacritic?"  The problem is that a lot of publishers do and if GB cause Halo's ranking to fall (so many 100% mean it likely will not) then people are not going to get their bonuses or hit their silly targets and GB could be discriminated against in the future - through no fault of their own.  I mean Halo is Halo and has bullet proof sales but metacritic has been named as the reason for sequels being cancelled before and they need to take responsibility for the stupid regard they are held in by sections of the industry.

I know you have been critical of Metacritic in the past e.g. how they convert 1up/EGMs letter grades in to percentages, so please consider a better way of doing things.
