What?!
If you say so, then you really don't understand what's better, you just look at what's newer.
AA2's graphics are worse only in those places where it was necessary, if we're talking about the correctness of the settings of graphic elements or the detailing of characters, then KK is a complete disgrace. I can't help but remember those buttons in the form of textures, eyes in the form of 2D sprites, heads in the form of a pot... And much more.
Even SVS is still worse than AA2 in some ways. SVS is much better than KK. If I compare SVS and AA2, I find it difficult, but SVS is probably a little better. AA2 has its own features, like hair sticking out of panties of different shapes, or look, AA2 has shadows and half-shadows WOW! Even despite the fact that the eyes are 3D, not 2D like in KK or SVS, where I did not notice shadows at all.
(Have you even seen pubic hair in modern ILL games? It's just a texture. AA2 It's a bunch of voluminous and good looking hairs, the volume of which is controlled by a separate slider, not to mention that you can select multiple hairs, and with AAU mods, you can choose from dozens of types, different hair shapes.(Just a more detailed example of one of the distinguishing features.))
