Studio9 is working on their take on the self improvement game phenomenon. Their DS game is a ground up developed title specifically for the Korean market and it packs in 3,000 questions.
So far most of the DS games in Korea are localized from Japan and in rare cases North America. Studio9 is sticking their neck out their a little since their project is original. Hopefully, their next project will be a music/rhythm game, considering this is coming from the same company working on Pump it Up Zero for the PSP.
