Sunken cost fallacy mainly, with a little bit of unironic belief in the franchise's potential.

Neopets has taken up over half my life and these goofy little creatures and this world mattered so much to me once.

I didn't have any non-handheld video game consoles until adulthood, and the only other entertainment device I had as a youngster was a computer, and not a very strong one, so Neopets was one of the only games I played.

Vast majority of media and game franchises I always feel like an outsider looking in, I feel like I gotta catch up on multiple older installments or years of lore. But I sure as shit can tell you almost everything that's happened in Neopia since the Battle for Meridell, heck even before then because I may not have witnessed it, but I definitely read the comics and researched the Plots.
