I just came across this thread for the first time, and want to say thank you. I don't have many games to add to the list, but the OP's tastes seem to be very much in line with my own, and most of the games at the top are the same ones I would have placed there myself. Similarly, comments on various other games down the list are in line with my own thoughts as well.
I'm a fan of both male on futa/dickgirl and dickgirl on male, but ideally in a way where the woman is traditionally feminine in most ways other than having a big cock and balls, and the sex between her and the male character is generally consensual and positive. As the top example on the list, the character of Amy in Lunar's Chosen is the shining star for me too, and her relationship with the MC is awesome. And more than anything, I like the dickgirl characters to be one or several among a large list of sex partners in the game.
I'm also looking forward to more content in Homelander (didn't care for the last update) and Power Vacuum. I liked Star Mars at first but holy cow that one went heavy in the exact opposite direction that I'm into.
A few that I enjoy that have this element as a smaller aspect are
The Inn and
Max's Life. Max's Life is an absolute odyssey of porn, and the futa aspect is small, but its good. The Inn has a smaller cast, and it seems likely that the futa character will be come back into the story, but development is slow (however the dev is great and posts here regularly).
