I ask this as a semi-serious question, but why is there no "rottentomatoes" equivalent for games?
Rather than taking the score of each review and averaging them all against each other, it just takes whether or not the review was considered positive or negative, and averages that out. It becomes less about what games are "better" than the others, just which ones are good or not. So long as it's above a certain point, it's "good". If it's not, it's "bad". End of story.
For example, if we consider LR:XIII's score on metacritic right now, it holds a 68.
Under the rottentomatoes style, if you split the good/bad right at 7/10 (with 7/10 going to good), it still comes out around 69% of reviews that are positive.
If you were to split it at 6/10, you're looking at 82% positive reviews.
The main issue I have with it is still the gripe many of you have with the current review scale, which would lead to a lot of games possibly skewing more towards good than bad unless the split was set high enough. But I personally think it would better represent the overall view of the reviewing public rather than relying on their scores.
