My last thoughts on the matter;
Honestly I dont really even see the point of working on 2 games at the same time that are so identical. From style/look and gameplay, they are essentially interchangeable. Theres unity/RPGM/comics/SFM's but Sins and Summoners are both Ren'Py games being made at the same time.
2 games that havent progressed much vs 1 solid game that could do the job of both pretty easily both gameplay and story-wise, not trying to shit on you Dev but you pretty much worked yourself into redundancy.
For those unaware Summoners Legacy is essentially a demonic/fantasy plot and Sins of her father is your basic slice of life/incest fuck-fest, these 2 core plot elements could have been made into 1 game pretty easily, the only setback was patreons stance on incest which could have easily been averted due to incest patches which are pretty much common place for developers to make who have their game on Patreon.
[Legacy of Her Father] *a combination of Summoners Legacy and Sins of her father*
A girl who had an estranged relationship with her mother and father lives in the big city with her little sister, they were really close growing up and one day their estranged mother comes to them bearing sad news (i.e sins), their father has passed away and she has no place to go. Eventually the siblings realize their bodies are changing, since they are their fathers offspring his ancestry/curse is now passed down and imbued in the girls transforming them into futanari (for the dad it was just a large dick) and granting them visions of their ancestors origins (i.e summoners),demonic lust and sexual awakening ensues....
Not bad for an off the cuff attempt to combine the plots if I do say so myself.
