Leo-J, someone who leaves rude comments and has flamed almost every Nintendo game in the top 50 of the ranking section really has no room to complain.
Just because you really like a game or think its good doesn't mean its going get the score you want.
Furthermore, what do you purpose be fixed? The opinions of the majority? Someone young as you might have a hard time understanding that there were great games long before the PS3 and PS2 and many classic franchises which happen to coincidentally be Nintendo in turn become some of the most beloved.
Incidentally if the ratings were all in favor of Sony games instead of Nintendo would you still be complaining of unfair bias?
