Fujino makes his own animations for scenes (at least partially) and tries to use good mods like skin texture replacement, nipples textures etc, while a lot of other KK-based games are just using vanila KK assets, animations, textures. So cards and scene looks like all the same and kinda meh
I'd say you can try
God's Blessing on This Cursed Ring! at least it is something standing out
God's Blessing on This Cursed Ring is amazing, not because the lewd scenes are admittedly incredible hot, but because it might be one the of the worst projects I have ever seen.
The developer must have spent at least 8 months or so, simply remaking the animations he already had instead of progressing the game, and it's not like the game was particularly close to a climax or anything.
I could spend an entire hour describing everything that is wrong with the game's development and how it pissed me off as a former patreon of the developer, but instead since this is neither the time or place I will say, that is a game to watch the scenes once and then never play it again until it's finished developing in 2055.
I went off that mini-rant not just because I was still pissed about how that developer decided to approach his game, but to praise Fujino that despite all his fallings and flaws, properly pushes the story forward with each update giving us new content no matter what, while never dropping the ball. (Besides his lackluster narrative regarding the characterization and themes of the original SAO).
