'Tis a sad say for the Chinese version of the game. I heard it on Discord, I would guess their player base is even less than Nukatu...maybe? Hopefully, because at least that would be a plausible explanation for such unexpected news. Rough super abridged translations...

The [Chinese FKG Team], after 1.5 years in operation, has made the decision to close the game effective 2017/12/8 - all game servers will be closed on this date. We have shared many memorable events throughout the life of the game; but however great any game may be, all good things will inevitablely come to an end (blah blah fluff industry talk). Due to our contract expiry and inability to meet forecast income projections, the Chinese FKG team has made the difficult decision to not renew the contact and end the Chinese version of FKG effective 2017/12/8. At the same time, Gatcha rates for 5 and 6 star girls will be significantly increased (not sure for what time period this is effective from, possibly from 11/23).

So yeah. Long live DMM FKG. That's all I can hope to say.
