I've seen quite a few people in-game say that our beloved Feral Heart is dying, but I do not agree. Many people join this game daily, even with the restricted registration times. (Average is 141 per day; forum stats (http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&action=stats)) With all of these new players arriving, it's impossible to say this game is dying! As long as people keep making new accounts, this game will be here for a while. On the forums, it lists how many people are on the server, and it always seems to be between 600-900 people. That's a lot online! Note that school/work could also be a factor about less people, but they'll be back in the summer or whenever they have more time for the game.
I think Feral Heart always had maps that were more popular than others. (I hear Bonfire was always "that" same Bonfire we know today. lol) I always see at least someone in every map, whether it be Last Cave or Temple of Dreams. Sometimes I notice there's not as many players on really late at night (EST), so time zones could be a factor to the lack of players in certain maps. In my mind, just because there's not 100 people in one map doesn't mean the people in there aren't having fun. I'd rather FH have one or two quiet maps to hangout in, rather than being squished in a tiny map like Atlantis.
Some of the reasons you gave about Feral Heart dying could be avoided simply, including "trolls." The block button is your friend. There'll always be trolls. lol
I know no one likes movie spam, but when people are advertising movies, I think that's the opposite of FH dying when you think about it. People are advertising their roleplays. You don't have to pay attention to movie spam, you could just turn it off or ignore it.
Reciently I heard a conversation in South Pole about the lack of updates for this game. It would be nice for an update or two, but people need to reconize that they themselves could make things for the game, including mods, presets, maps, and the list goes on. I love that about Feralheart; it's customizable! So what if there's no prey? Go to another game then.
Also, the lack of typos in Bonfire doesn't mean that the game itself is dying. xD If whether this game stayed up rested on how many typos people make, this game would be long gone. Same goes for wolfspeak. People might have just noticed what they were doing. I'm sure there were always wolfspeakers, after all, they didn't originate in FeralHeart.
In conclusion, I don't think Feral Heart is dying; just about the opposite. :)
