It's been a while, here's a big one:
Taking into account that we´re nowhere near the next version coming out and thinking about it for a while, I think I found a suitable idea to fill or give a final goal to a game and a reason for the pregnancy mechanics.
Reviewing stories of one of the coolest and unique authors in the manga, Junji Ito, I saw a story again that in fact, some of his ideas can be applied here, from Ma no Kakera the sixth chapter in particular, that of "Black bird "given that when a game begins, after defining in the survey (what is accessible) about our positions on some things, we start in the orphanage as if nothing strange happened and the world was normal, from there we all know that when we leave the orphanage the first meeting will be activated where the mechanics of it are explained to us, to which regardless of how we solve it, a person comes to us and ends up giving us the pepper pot and leaves as if that were the most normal thing in the world, That is where and inspiring us not only in that story of Junji ito, but in several, the MC in dialogues for the same may think how strange the "normality" that these events occur despite the fact that in real life they should not be.
Then, I think that after the first week passes (which if or if it must happen for date events to start activating) and regardless of whether we have managed to maintain our virginity or not, as well as there is a night monster, it should there is a creature that after said week appears and binds us to a curse, said in which it is imposed on us that if we don´t pay said creature some type of currency that can "only" be obtained by carrying out sexual or malevolent acts (the malevolent evidently with less value than the sexual ones) the creature by the end of the month will come and rape us until we die, only so that due to so much violation, our body has become pregnant (regardless of gender) and the son or daughter that we actually had , is our reincarnation.
And as you can imagine, because of said creature and its curse is that all the inhabitants of the city at some point or another carry out said acts or see it normally, since they are also tied to the curse and nobody talks about her because the curse one of its conditions is that you cannot talk about it. So the objective to achieve as the closing of a game, is to find a way (by any of different means) to break the curse or perhaps, to gain control of it to give an idea.
Mechanics that are born from this:
* Regardless of whether it is due to the creature due to lack of payment or our choice (due to the love interest for sweet or "acceptable" for any other generic NPC), the pregnancy mechanic would become as mentioned in past entries as it happens in Lona, in an extra life for when, either our MC reaches a critical point of stress or some bad factor dies or due to some event that kills us and since the curse exists, no one realizes what happened and also in this way when said reincarnation occurs, the love interest or the father of the baby also forgets and this factor is solved. In addition, just as it happens with the child that can be given birth by pregnancy from behind, the baby isn´t a living entity but rather, a vessel for our being in case of death, except obviously to avoid being stolen from us, we would no need to take care of it and therefore, it is not necessary to add new care mechanisms. In addition to evidently, depending on the species of the father, the next reincarnation would already start with that species or else, a cross if it is compatible (example fallen angel and cat) although this to insentivate the reincarnation, would imply that the transformation would have to be hardened so that not so easy to achieve.
* For MC's who seek to maintain virginity and be an angel (difficult mode) as well as we can reincarnate and for NPCs who at first don´t seem to be affected by the curse (example, Eden), apart from the currency of sexual or malevolent acts, there should be another way to payment (example: Eden can pay with life taken [hunter] or Robin with money or purchased goods [money]) and we, either by one way or another pay, although as happens with Barley, by paying the payment in this way every month go up by paying this way. Therefore, in this way there would be an insistence (in addition to personal curiosity) to explore different events and points on the map to find a way to get rid or control the curse.
Note: I forgot to add it, but for the virgin MCs and who reach angel (or not), their form of incarnation could be through faith to the church (and some event) or, by some other means that is related to what is right, pure and good.
Anyway, this is just an idea that comes to me after I saw the story of "black bird" again, the idea that we either sedate or resist the wishes of the creature so that we corrupt ourselves, the one that in the end until we (as happens to the game in my opinion at the moment) we don´t start to move to do something to break the curse and more than curse, the ponds that it brings, in the end either because we end up breaking (due to attributes negative already very high) or because we don´t handle the situation well, this in the end would cause that MC unless cheat is used is insurmountable and the only option is to start another, referring to the fact that at the end said MC or life died due to its lack of good handling.
With nothing more to add, I leave.
P.D: For Vrelnir, I know that maybe you already have an idea or none at all, but in any case, just as there are fanfictions of things, this little madness that I thought is my way of saying, good job, keep doing bad good.
