I am the KWING of this genre. There was a phenomenal show on PAX yes the Canadian local station called “Young Blades”. It was SO good. About the three musketeers then a girl disguises herself as a boy to join them. I wish I could find it on the internet somewhere.

A tale in the desert was kind of Minecraft before Minecraft. Such a great game.

Nexus Tk kingdom of the winds was also great until they changed the system for leveling.

Tons of books or book series like Darren Shan saga and tales of ambrose. This great series by Christopher pike about vampires

My entire life has been spent in this genre 😆
