That makes no logical sense, if the same Devs from Japan owned the game on Nutaku then it would still be making enough money to stay open, hell it wouldn't need to make extra just break even and they would still be in front due to Japanese sales. Are you telling me the Jap ver is also closing? If not then it's much more likely they had a western company (even if it was a subsidiary) doing all the translations and server side here. That company is the issue here, that and the fact that western gamers simply do not spend on games the same was as the Japanese do.
