Sexvilla is good, but sometimes I think they take the clothing and locale options too far and don't spend enough time on other features. And the game is waaaaaaaaaaaay too expensive. $50 would get you like, 5% of the game. And the descriptions of what you get for your points are awful.
Things I liked about it however:
-Recently added sweat (specular map) -- super awesome
-Multiple voice sets
-Story mode (though I don't like that you can "lose" and have to start over)
-Unique poses that use the environment
-Fetish club area
-Cumshot cannon, usable any time
-POV mode
-Vaginal or Anal available in any pose
-Threesomes
You do already have some things they don't though. Your animations aren't just the same thrust over and over, there are... "flourishes." I would like to see a flourish button however, for when you want an extra oomph. A separate button for each partner, actually.
And you have the Sex Variety Pack. I think that's much better than going into a menu and selecting a slightly different pose. The buttons are right there. Sexvilla doesn't do that.
Your game is also moddable. I do mod games, but I'm not sure if or when I'll mod yours. I'm more of a scripter; I've never done texturing or modeling. Though I love having the option. On the other hand, Sexvilla lets you "mod" faces and bodies in-game. But they don't let you hand-craft clothing or anything. And their face editing tool has too much freedom. It's really, really hard to get a face that even looks humanly possible.
I played Cherry Dolls (also by Ripened Peach), which was sort of like a dumbed-down Sex Sim. I don't even see a link to it on the
RP site anymore (or any other games for that matter... what gives?). It did have a sort of cumshot mode though, which I liked. When the guy comes you could either do nothing and cum inside her or cum on her face or chest.
I played Virtual Hottie, but it was nothing special. The voices were almost not even there, you could never tell who was orgasming when, I couldn't even figure out the arousal meters and there was no manual to help. There was no customization aside from dick size, boob size, 3 skin colors and 3 hair colors. Even the animations were lacking, with clipping issues all the time.
eGirl was fun for a few minutes, but again too simple. You get a girl who takes off her clothes and starts using a dildo on herself. You get to choose between either an impossibly large and painful dildo that doesn't remotely fit into the model or an even bigger one. She has a few poses and a few backgrounds, and again, very few voice files.
Any other I've come across (believe me, I've looked) has had graphics too poor for me to even consider. I get that there's a good reason to keep system requirements low, but I have a screaming fast gaming machine and for me, more is always better. At least make it optional. I hope you're making the game with the future in mind. Some long-term games make upgrades to their engine.
I know you only asked for ones that we liked, but there is a lot of garbage in this genre.
