ok so like everything in this is something I agree with, but some of it has lore reasons and story stuff as to why it hasn't happened, Logan's stuff is what I'm gonna start with, namely his dialog.
I agree with the less rough after catching up with story stuff point as it happened with others so I don't really got any explanation for it or defenses. The visiting the house thing actually has a mini conformation when you speak to him about it afterword's at the sawmill, when asked about doing it again he says later because he felt embarassed about how he acted/what he did. so I believe that's coming eventually just not sure when. also seeing Logan get closure should absolutely be added eventually and again is something i think WILL happen based off how heavily Hyao speaks of how Logan was affected by her betrayal and how hard he looked for her at the beginning.
The next thing I'm gonna talk about is the farmhouse, most of which is all stuff I just genuinely agree with. the Gloryhole being able to choose which side your on is something I thought might just be a canon thing but its random, which I kinda wish wasn't true for those of us without interest in being on top, the Ste things though are all I'm pretty sure guest content? so like maybe eventually he will let us bottom or he will only let us be on top, depends entirely on how the guest writer creates the character.
After that lizard tribe stuff, and or stuff I think for certain will be added and other thing that when I read you say I instantly thought "oh dear lord please add this it sounds too good to be true I want it." that last thing I said was mainly towards the three way, I'm 90% sure were going to eventually gain Rhot's trust its just gonna be a long grueling process like it was with Logan XD. also bottoming for Roushk should prolly be added eventually for certain cause he has hearts and anyone with relationship dialog/hearts should be able to let you do either side with them one way or another.
then the other things you mentioned, specifically magic and the inucbus. another dear god please add these in the game, especially magic. they both feel less than likely however due to certain factors in the game, like how incubus' have never been mentioned before and I don't know if they even exist in aigran. magic is just difficult for a different reason entirely, how would it be implemented? that is a major game changer mechanic and could mess with a lot of stuff in game because of how vast and massive magic is of a topic and how much might need to be added. like healing magic, damage magics, buff magics just for basic stuff. however your idea about magic weapon's is both interesting and possible already in game! the necklace you get from the witch or Othra and Orsu's amulet and Razit's spear are technically magic already because the spear is better against special enemies and the amulet gives certain buff's when wearing and getting a good sleep! so magic weapon's are a very large possibility but magic is less of one and incubus' would be an amazing thing to add but very difficult.
you and I seem to have similar idea's for this though because 2 of your point's are things I was thinking I would love for this game a long time ago, so guess great mind's do think alike ay? but seriously your last thing saying how much you appreciate hyao and his effort into this are most likely incredibly appreciated as he is working really hard to update this. so ima join in on that and say thanks hyao for creating this awesome game and sharing it with us! you rock man!
