I'm pretty sure you guys have thought 10 times more about certain aspects of the game than cbob and Marty. Don't be disappointed if the end of the game will not be as interesting and sophisticated as your own ideas and fantasies. A lot of curious and non lore things were just put in the game (or were indirect consequences) because of wishes and questions of MITY's patreons.
Marty said that at the beginning of development they wanted to stay very close to the original but the more the game evolved the more ideas and wishes were integrated. And for that in most cases they often used easy and fast solutions so it wouldn't slow down the development process too much.
For example, youth potions are a really stupid thing when you think about it. But without them we wouldn't have young Toph and Azula in book 4. So there's no explanation or lore for it, it's just there to provide access to more lewd fun.
MITY never wanted to have Mai or Jinora as main characters, feedback from his patreons changed that and over time he also got used to more lewd alternatives as he planned to. (Just look at the tags)
For all of this they needed to integrate it in a kind of plausible but not too complicated way. That's why more often than not there's no sophisticated, far-reaching plan and/or solution for certain "riddles" of the game.
There are exceptions to this though and that's both fantastic and annoying. Fantastic because lots of people can find small, new secrets when playing a second time, annoying because sometimes it's quite complicated and unclear to get them. (Like Pema having sex with MC in love route)
Which brings me to the second point I wanted to talk about. Am I alone in thinking that Korra's and Opal's last scenes were amazing?
I'm team Jinora but the new Korra scene is my new favorite right now. Maybe I'm just a sucker for short hair Korra but damn do I love it. Just wish we could skip the anal part if we wanted to.
I also have to say I didn't expect Marty to go all the way with Korra in this scene. As they say, "To each their own" but that's a notch too much for me to feel comfortable. Always good to make such things optional though.
Dude, many asian women look 13... when they are 30. There are also Western samples of this but a bit rare.
I think I posted that here already but this girl and pose always reminds me of Toph at the bathtub :
So, yes it's possible to find such women. Loli Korra though...
