I have like, one really vivid memory of the "old" FeralHeart that I think about a lot that makes me super nostalgic. Listening to that specific song in Ficho Tunnels (Moon Temple, I believe it's called) while sitting around roleplaying or wandering the map on my own brings back so many memories and good feelings. I used to play this game a lot when I was sick with mono and other things, and just remembering that brings the good feelings that had come with it. I wish I could go back, sometimes! It really is the soundtrack that makes me nostalgic...
Also, the absolute chaos of Bonfire before they added lonely cave. The computer I had used was old and pathetic and it took me forever to get away from the spawn point. I was so relieved when they added Lonely Cave. I also miss the random Lion King roleplays at the little cliff of Bonfire, or the random fox and wolf pups wandering around.
I also miss when custom maps weren't super duper complicated! It's such a weird thing, but I loved the simplicity of old custom roleplay maps that just used the default FeralHeart items. I had some of my best roleplays in those maps. Also, when everyone used Skype groups for their roleplays instead of Discord, LOL.
Also, the husky and arctic wolf roleplays in South Pole. I've been itching to be in one ever since, but I feel like it's too late now, LOL. It just seemed like there were simply more roleplays back then, and like someone said earlier, nowadays they're basically all on Discord. It just felt like the roleplays back then were a bit more... genuine? I don't know the right word for it. Recruiting at Cape Island in Fluorite was one of my favorite things to do. Now everyone just runs around in the chaos that is The Grounds.
