I understand your point, I supported this new version of the game for a while (until i had to cancel all payments, I hope to be able to do it again soon) for a simple reason: the art.
I don't know what are your criteria to enjoy a porn game, to each his own, but for me art is the most important, if not the only reason I decide to play/support a game or not.
So, yeah, this new version of the game is a little grindy, the goals are not clearly explained, sometimes you need an insane combination of conditions to unlock a silly gallery or move on in the story, but...
...Aleksey90's art is just absolutely fucking mind blowing. Compared to DS's boring little 3D dolls with their frozen corner-lipped smiles, Aleksey90 finally gives justice to the house's females (and above all to Goddess Kira). ALeksey90 is so talented he can reproduce the game's original art to perfection, and make it a lot, lot better.
If you want to finally see top quality KIA (Kira in action) and brilliant art, yeah, it's worth supporting it, or just play it.
Beware of the bugged versions though, several bug fixes are constantly needed for every update.
