@Maasw First of all, this is the Wiki forum, and I don't think the word that you ended the sentence "because the raters are..." on is allowed. Maybe you should've used wimps instead.
Second of all, while not on a very high scale, the Tamagotchi franchise has had a fair share of...content that wasn't so G for General or E for Everyone (for example, alcohol consumption was a major plot point for the vintage era, the Predator mechanic in some earlier devices could be seen as violence that could lead to Tama-Slaughter if not tended to accordingly, and let's not forget about the anime, which had an episode that had a bait-and-switch joke that displayed a shoulder massage that was initially shown as sexual assault in progress.)
The point I'm trying to make is if Tamagotchi Adventure Kingdom gets an E10+ rating, it'll probably disappoint you, but it won't be surprising to me and other fans, especially if it incorporates LGBTQIA+ themes, which the United States as a whole is unfortunately not universally keen on the idea of letting kids know that such people exist and deserve respect and fair opportunities, no matter how SFW such a moral turns out to be.
