They are releasing alot of games, but their sales are always way way below 1 million.
Persona 4 may be different but even then it took a long time to get high numbers. So I am curios how can they be so profitable, because from what I heard they are actually doing pretty good. They sell some niche products and if we compare their sales to what western publishers would expect from a game they seem to be doing pretty bad, but that is not the case, and they always turn a profit.
I know that releasing on handhelds will keep costs down, but they still have a lot of voice acting in some of the games aswell as high production values.
