From what I have heard, when FH was first created, registration was left open for quite awhile. But it obviously wasn't working out, which is why they are doing this now. And it has been this way for a few years now. The same thing would probably happen if it was opened all the time as it did when it was first created. The staff do not want to mess with the servers constantly going down. As Hakumi stated, there are always new people coming in, so in all reality, this game is still rather active. And a lot of games slow down after a few years, it's just how it is. But as of now, I honestly don't see Feralheart dying out anytime soon. And I really don't even see it as a ghost town.
