Any similar games? Doubt there will be any better ones but at least close to this level.
Broken Dreams if you want a really good story, it isn't complete and there is only a bit of nudity so far and only 1 sex scene(2 if you join the Patreon for the newest version).
AIRevolution still doesn't have much content yet and the story isn't all that so far but the animations are great.
Succubus Kingdom is still in very early development but I'm sure it's going to be a banger. One thing that Goddesses' Whim does perfectly is making you genuinely love the characters, I have a feeling Succubus Kingdom will be the same way.
TwistedWorld Remake if you're into some kinky degen shit. This is the remake that is still incomplete for Twisted World Classic. The classic is already complete if you want the full story but it doesn't look as good.
Story H-Scenes
1. Broken Dreams 1. Goddesses' Whim
2. Goddesses' Whim 2. AIRevolution
3. Succubus Kingdom 3. Succubus Kingdom
4. TwistedWorld Remake 4. Broken Dreams
5. AIRevolution 5. TwistedWorld Remake
All of these are good in every aspect even if they are lower in my rankings. Goddesses' Whim is still the best overall so go ahead and give Ncrow your money.
For Broken Dreams I suspect the dev might be a bit of a pedo, not certain though, but the story is just so good and the game is so well made that it feels like a sin not to play it. Other than TwistedWorld, all those games aren't any worse than Goddesses' Whim on the degen scale, and they all give you the option to avoid anything you might not want to see.
A good one to add would be hero's harem guild by komisari. The over all feel is very similar to goddesses whim and the dev is currently working on a massive update that will add lots of new content. Definitely recommend checking it out if you have a chance.
I've played it and I thought it was just decent in every aspect, I didn't think anything set it apart from the others. Also having to wait 2 years for an update is a bit of a turnoff even if it is a big one, I will still play it though. And I hate those character models on the Renpy engine that look like shiny inflatable balloons, the maid being one of them.
