The chart numbers you see are merely algorithmic and somewhat arbitrary because they are based on community voting. What this does give a representation for is popularity. There is truth to some of the stats you see, and if you have played the game yourself it becomes apparent in more ways than one. Because it's more or less the first month of release, the numbers are all hand in hand and quite dynamic. So the positions of rank fluctuate every hour. What hasn't changed since I first saw this was the top 3 positions: Rosalina being indisputedly #1, and Zero Suit Samus and Shiek going hand in hand, in which this metacritic-esque community believes that the top 3 all serve this check-and-balance system to create this balance.
The rest of the list is up for constant debate and doesn't really hold any meaning. The statistics that stay constant are what you keep your eyes on and what you observe in-game is also something notable. We also need to wait for tournaments to truly craft a tier-system at all. Still though, it is apparent that the top 3 are the characters to beat and are of great interest.
For any of you smash bros out there, what do you think? What changes in this sequel do you like or dislike? What does your main lineup look like now in contrast to Brawl? Mine personally is now Luigi, Wii Fit Trainer, and Sonic (and Palutena is climbing her way to my liking for main lineup.)
There's a lot to discuss...
