Final Fantasy XIII prediction: There will be sixes and maybe fives amongst the review scores. Metacritic score will drop to low 80's, maybe even high 70's. JRPGs this generation have struggled to score higher than a metacric score of 80%. FFXIII has had mixed reviews. Just you all wait and see.
The more critical reviews should not be ignored. Ignore the 100% review scores. Look at the lower scores. If a game gets 10's, 9's and 8's. The reviews with 8's and 9's would let you know what is wrong with the game. 10's would have little or no criticism of the game. Every game has its faults.
