81 is a low score...
81 is a good score and the game will sell very well with no negative impact from said good score.
Look if you want you can read the full text reviews, nobody is stopping you. However don't take the scores away from us that care. I look at the MC, if its under 85 I close the game, if it's over I might read a couple of review snippets in the list and make a decision. No way am I going to read a full meandering review though. I don't need to read 2000 words when I can look at the score in a second. You can make everything long and convoluted - including explaining math equations via thousands of words when a simple formula is enough.
