Hey, Ronny!

I might be the wrong person to answer this, as I am not very well versed in the Visual Novel genre, but I will try my best since no one has replied to this thread yet. HuniePop is a hybrid of Dating Sim and Puzzle, a fusion I don't think has ever been done before. The Dating Sim genre has not had much prevalence outside of Japan. The Visual Novel genre is somewhat similar, but oftentimes not as interactive as Dating Sims tend to be.

The only game that comes to mind that is somewhat similar is a game that hasn't been officially released yet. It's a combination of a card game and a relationship simulator called Luckless Seven. I backed their last year, but they offer their Alpha builds for free on [url=http://www.indiedb.com/games/luckless-seven]IndieDB. It won't be anywhere near as sexually explicit as HuniePop, but I have really enjoyed what I've played so far.

Well... if you are looking into 'lewd' content, then Purino Party on Steam. I belive you can ffound a legal patch to uncut it. Basically it's HuniePop, with more of a Visual Novel parts.

Huniepop is my favorite game once but after finished it i was getting bored so created a list of
games like huniepop

Hello, here are some games like Huniepop-The Flower Shop, Kitty Powers’ Matchmaker are best.

The ones, I could think of are

-Crush Crush (also the other games by Sad Panda Studios) &
-Love Esquire

The Gameplay is not so similar. However,
they have a very similar style, since they are all dating sims from a non-japanese company, original language is English. They are all fully voiced in English and share a somewhat similar humor.

I hope, this helps. I'm also always looking for similar games ;-D
