This is actually a real problem, subjectively and for me only at least.
It's pretty hard to have a decent conversation in Graal because most people are around 12/13 and lets face it... Kids are kids. They don't act mature because they just arent. They arent supposed to be, they're kids!
But this leads to the average conversation on Graal to being around youtube comment level. This can make things frustrating for us old guys.
I can't say it used to be any better. I started playing Graal in 1999 when I was... 12 so I'm sure I was just the same. I feel like it was though, but then Graal was full of quests. Lizard shield/sword, lots of hearts, tons of new weapons. Some of the quests were absolutely massive (Thyme's was a later one, but it took hours and hours. There was a cool "retro graal" quest with a time machine that was long. Before then there was the actual "4 graals/golden land" quest that was long.)
I think then people focused on the game of it all while playing so being young didn't matter much. Now it's more of a chatroom with swords, so kids have a lot more opportunities to say and do things that make it obvious how young they are.
Sometimes people ask me why someone so "old" (mid 20s is not old!) plays Graal. The only answer I have is "nostalgia." It's weird though because these kids are too young to even relate there, they're not old enough to have anything to be nostalgic for!
