check out the graph,
this game get my vote for the most equal game in history between all 3 territories.
The MK series in general is the series that seems most equally popular in all 3 territories.
Like SSB is not as popular in Others, and Metriod tanks in Japan, 3d Mario is MORE popular in the west(still popular in Japan), and 2d mario is more popular in Japan.
If you think of any other series that are like this one please point them out.
The user base for DS is the most equal userbase in history(for now, I believe NA and others will pull away from Japan in the next 2 years) all 3 territories within 10% of each other.
Main reason this makes me think is MK:Wii will be the FIRST console MK to be realesed on a platform that is Popular in all 3 territories(GC and N64 sucked in Japan, SNES sucked in Others... Actually the Wii is the FIRST Nintendo console to preform GREAT in others)
psn- tokila
add me, the more the merrier.
