America? America loves the Nintendo Wii. Europe? Ditto. And Japan? Man, Japan is bonkers for the Wii. What about Korea? The country finally has an official Nintendo of Korea branch after years of going through shady third party distributors. According to Korean site GameShot.net, the Wii's first month performance there is only 35,000 units sold out of the 50,000 units released by Nintendo. For game software, Wii Sports sold 30,000 copies, while Swing Golf Pangya and Zack & Wiki each sold about 8,000 copies. FIFA sold 2,000 copies. It seems Korean gamers have better things to do than play Wii Sports — things like waiting for StarCraft II.
None of the big three can get any sort of foot hold in Korea and it's biggest reason is simply for years the big two, (And later the big three) gave Korea even worse treatment then they give the UK. During this time, PC's ended up getting more widespread within homes, internet got a good penetration rate and then RTS's and MMO's caught hold, then fire.
It's going to take years and years and millions on millions of dollars for any of them to really make much headway and in the end the only way any of them will be via a MMO. Nintendo's best bet is via portables as even the errection worthy cell-phones that Korea is known for don't have very good games.
