Just goes on to show the number of Nintendo fans on this forum. It's a sign of a forum not growing and not getting new members. Very much like gamefaqs.
Or it goes to show that a lot of members grew up with Nintendo and vote for games they are nostalgic over.
And this site has always leaned more towards nintendo than Microsoft or Sony when it comes to these competitions (if you need proof you can check the links in the OP).
