  1. If you like funny AVNs i would highly recommend classy lemon’s works: Projekt:Passion and After the Inferono

  2. an amazing and intriguing story from beginning to end. The characters are wello fleshed out and the incest is done IN THE RIGHT WAY. Sex scenes don’t feel like theyre there just for the sake of it, each sex scene is fully and emotionally fleshed out. I don’t personally like the art style, nothing against HS AVNs because the art in ETERNUM is amazing, i just don’t prefer the particular character models in this one. But despite that, i followed through this AVFN because the community said the story and engagement was amazing, and i WAS NOT DISSAPOINTED.

  3. it should be considering the game is made by the same people and also within the same universe even a few of the mentioned places are within both games as are a few other chars look for them in Eternum one should stand out right at the start of it when your char mentions his home towns collage and who went there in the past

  4. A funny, heartwarming, and consistently enjoyable AVN. Plenty of lewdness but not gratuitously so. The story’s goofy dark-fantasy elements are not taken too seriously and the humor provides a levity that is crucial for a game about banging your step-family and their friends. Stabby Mike is a top-5 secondary character as far as I’m concerned. I absolutely recommend giving this AVN a go, as well as checking out Caribdis’s current project Elysium.
