Hi, thought I would answer briefly here. I am reading the developer's thread section from like a year and there's some really good stuff in there that is helping me more than I expected! I tend to forget the devs too much on this site...definitely my bad.
There is a character in KG that cannot be killed no matter what because she is a major character in a game set in the future. In that game (and the other one more on that below) players will be able to "choose" one of four world states or a combo possibly of two of them that ended KG (I can't really see how I can save each ending over easily otherwise) and a few other facts about major characters. Now most of these characters are long gone as it's set in the future, but it may impact how that surviving female may act/talk about the past and what she does, etc. The male protagonist (who he is) may be impacted by the canon choices/endings.
Game # 1 will be more like a hero's journey (or villian) action/adventure sex/erotic game, I am only likely to write and support it not do the entire thing given time constraints. (I just don't have any more bandwidth) Much more "traditional" game with action/adventure and women to romance/harem, etc. But it will have a lot of choice/consequence. This game will likely start work sometime later this year but I will not be the lead dev but writing support. Not likely to have any femdom except (up to her) very vanilla style/gentle fun stuff with a specific romance possibly that is nowhere near as dark/harsh as KG.
Game #2 will be only femdom and set on one specific planet in the overall universe post KG and Game #1. I will not start this game until KG is finished. I prefer not to even share any details about this one yet, as I want to focus on the current game of course.
