I haven't seen a single hentai game with a decent engine, smooth and unbuggy gameplay. The visuals are important for sure, however it's not the only primary thing in games, you may jack off just as effective as to any other random online lewd imagesGame engines are nothing compared to the quality of the image presented.
If the visuals are awful or uncanny, that is what truly matters
Engines are just simple tools to acquire the entertainment, for them I personally feel no regard
True! To me unity is the least evil among other engines, it's still buggy and it cannot handle many assets and consuming tons of ram, but some cool devs do figure things out and make decent games on this crapUnity games have good mechanics visually but hard to rollback or replay gallery.
RPGM is just meh imo.
I prefer lewd games with 3rd person characters and character customization editors, i enjoy variable scenes/poses/clothes and other tasty features of this kindThey aren't real games
