Never heard of Goddess' Whim but I tried out Succubus Kingdom briefly, it's early so I decided to wait but the "graphics" of that game are absolutely brilliant, I'm definitely keeping my eye on it.
And yeah, LiLs anims are the bare bones, unedited KK anims. It has
very good lighting (as mentioned many times by others) and the game looks good, but there's nothing particularly interesting.
In current, you just have a dick clipping through a character in a 2 second animation loop with some frankly terrible camera angles that massively limit what you can see.
Compare "Being a DIKs" animations to older games of the same engine. That dev won because he did better.
I don't want to list out every detail that makes LiL behind the curve but you can see it pretty easily with only a short look. Static, bad angles, limited movement, dick clipping, and little to no physics.
Might sound dumb to harp on the quality of sex in a sex game but... This is a porn game forum, if you have the best in story and characters, why not take that extra edge and have top tier porn too. LiLs anims are fucking miles behind the competition and even though the aforementioned writing is, IMO, unparraleled; he falls behind in the most broadly appealing aspect.
Getting your rocks off.
Also if I've done a bad job of communicating the differences I'll post an animation from LiL followed by one of another game, if thats allowed.
