Ironically I was going to make a post similar to this: Adults playing with children or vice versa.
Either way, when you think of it, people will see it as another mmorpg game that anyone can access. In other words, free. FeralHeart is easy to access via download and people. However, the [older] people, who we are addressing that plays FeralHeart, played when they were little kids. Just like you and the other members who are playing now.
You and the younger members who play FeralHeart will eventually play until life grabs you by the hands and pulls you away, in which happened to users back in 2011.
The users who you are probably running into are old members who are wanting to relive the nostalgia, and I don't see anything wrong with that. People who I've met so far are just below or above my age range, which is fine because we all have the same interest. FeralHeart. Myself, including the others, has said they don't feel they match their age. I've met people who said they're a 20 year old trapped in a 16 mindset, and I believe that's okay because I am currently experiencing that. I don't think like a 20 year old or believe I've mature as one.
Because of kids becoming uncomfortable I do think the game is divided in a way, but not entirely. I've met some youngsters who are incredibly smart and mature during our small talks. Some members mingle for the older members and some dont, and again, that's totally fine. Its about you an you're experience that makes up the memories.
Overall, Feral Heart is for everyone and people from all ages joins, and no one can stop it. I wouldn't see it as an issue as there always a group of different ages around, you just need to find the right one I suppose. For me, I just mingle with everyone.
Also, to close off, I will report the person who's lying about their age to just to talk with younger members, which I find just disgusting enough. If you feel harmed or uncomfortable, the FeralHeart staff is here
Just my two cents.
