Reading this CYOA for the first time (this page especially) upgraded how I look at growth, and even shrinking scenarios. I was never into breast/muscle/bodypart expansion, or transformation. But when coupled with the concept of personality shifts, it really speaks to me, and helps me understand the appeal. The way suppressed or hidden urges can become public when no one's able to stop a girl anymore; the way a girl with existing power might end up using it differently or becoming more/less responsible when she can see everyone looking up at her; or just in how the excesses possible at a titanic size can be mind-numbingly addictive; that kind of stuff is now somewhere in my mind every time I really sit down and think about size change.
It's also made me realize why some "canon" giantess characters get comparatively less art or literature (though that's been changing recently). We've already seen how they act at giant size. The REAL fun part is the unknown, speculating what aspects of a person might change, or become more prominent, or remain stubbornly intact, when they experience a huge boost in size/power. (Or for that matter, when they have a tiny person in their house, and nobody's watching them.)
That, and the CYOA recognizes itself as a conversation/story/scenario starter, which doesn't necessitate RPG mechanics or even board game style statistics. In a brief, single-player thought exercise, things like "multiplayer balance" or "level progression" don't really have a place. Even before the bonuses on Page 3, choices feel less like limitations, and more like fun-enhancers to give the growth story some conflict, or a common language for players to express and exchange outlandish ideas.
Granted, I've had a blast with deep, numeric point build stuff, trying to manage and shuffle limited resources. But this one essentially has those meta/supplement/extra-points CYOAs built in, while simultaneously questioning whether they really bring more fun or better posts out of a build. It's at once a surprising notion to see addressed in a lewd CYOA, yet makes sense: the concept that "imagining limits can be fun" isn't that far removed "imagining a huge body limiting your movement can be fun."
