Turning the tables isn't something I am very interested in, but I will likely have a version of Kira on more equal grounds, as you say, it's just a matter of writing the path and the scenes. Eliza though is in it just to use you, so she isn't going to be convinced, even assuming you could break her control. Other things include Jin having a path where he isn't the dom, and perhaps Kairos (if I have enough time before 1.0 eventually comes out to add a different path with him).
I thought people would remember one of the persons at the stalls was advertising her maps, but I guess that was too much (and I guess some people don't talk to everyone, regardless). I'll give her shop a sign, and put a few more maps on display, that should be plenty to notice and remember the shop. If you do remember more situations, please do let me know. The game isn't designed to give super precise instructions, to encourage exploration and experimentation, but that doesn't mean I haven't left behind some blind spots, so I might change things if I agree that something isn't indicated or hinted at well enough.
Golden Leaf will have more content added to it, for sure.
We'll see about Keiko (she is already involved in some of the mind control stuff as another target, but having some normal content with her might be cool). The maids won't for sure, though, other than some very specific stuff I have in mind.
I'd like more side content. Specifically, I'd like more small locations on the world map (so I can give rewards here and there for exploration), and a few things for the smaller towns/cities. The problem is that adding new jobs doesn't make sense after a certain point, so that leaves quests, random events, and mini-games for the most part.
Some anal content will make it into the game (there is a little amount of it already, but I think more should be a good thing as well). Any suggestions as to who you'd think would fit the bill for this?
I do have a plan for the main content in the game already, but I try to listen to suggestions, even if most of the times I might have to turn them down for one reason or another, it doesn't mean that it can't be helpful.
