According to BigBen Interactive they released Dokapon Kingdom for the Wii in EU in 2010.
They're a French based company but they also have a UK website so I assume they released copies in both countries, or at least gave it a bilingual option in whichever country they released it in. However I've never seen a copy for sale in the wild and Ebay/Amazon just bring up NA/JPN copies.
A google search just brings up torrents which is not what I want. Does anyone know if this actually got released over here?
