So we have, count them, 1 CON and that drags the game from 100% all the way down to 81.2% ????????/
does not make sense.....
You have to be kidding! A pros and cons list is nothing more than a few words the reviewer determines at the end of the review. You don't make a list with all the pros and cons of a game in it. The list would be simply too large.
I know of no magazine or site that uses the pro and con list as a basis for the end score.
