I'd like to caveat this by stating that this is not a H game. But it does have H game elements in it, so while I would critique this work as a game, I will still put an emphasis on the H game elements.
Story
Pretty decent. Much better than most H games out there, with a fairly fleshed out world and its rules are well set. Reasons and rules are established as to what magic is, how mana is made (take a guess), and why slavery is widespread and accepted.
Basically, you're in a world where magic is so powerful the greatest power is indeed the mage guild. Kinda like how Arrakis is technically the most powerful planet in Dune because of spice. You play as a person who wants a slice of that pie, and so your involvement in that world is pretty much determined from there.
There are 4 different hubs, each with different races/species and with their own history. Neatly done. For once in a brothel management game, you're not just trapped in one piece of land whoring out shelves of ladies.
I wont spoil this game's plot here, but suffice to say this game's plot is well written and thoroughly deserving of that 'adult' game status.
Gameplay
The best description of this game is pseudo-pokemon. Except your pokemon are slaves of various races/species, and you can quite literally fuck their brains out. Capturing your slaves follows a fairly predictable plan, like pokemon - knock them out, tie them up, and then they're yours.
Except, in pokemon, it is established that once they are captured in a pokeball they're pretty much subservient to your wants. Your apparent prowess of beating gym leaders appeal to these creatures for some reason. In this game however, your newly captured slave is (as most would) predictably not very happy being your slave and will not obey your orders. So you break them, physically and mentally until they are. God, imagine needing to do the same in pokemon. Yes, there is rape in this game, and yes it does have gameplay significance.
Your slaves can then be trained for battle, and grinding xp is as tedious as it sounds. You beat lots of zubats for xp, like pokemon. There's no overpowered skill here; its plain grind. Its entirely possible to have a core group of ladies who are ugly as fuck but because they kill things efficiently, they're more valuable than your pretty elf princess in her skimpy negligee.
So how does the sex hold up? Well...pretty bad. The reason why I caveat this at the beginning is simply because the core H game here is text, no images. No drag, no VA, not even a disgusting ahegao picture, just text and you clicking. There are a few scripted characters where there's AN image of sex while the text screen bleats at you, but on the whole its 99% sexting, 1% image.
In short, if youre going in here thinking of brothel king, you're likely going to be disappointed.
Emotional Progression
And yet, despite its subpar H gameplay, this game makes me feel more for the girls than brothel king ever did. Having spent so much time with them, grooming them and fighting off wolves and bears, whenever I do have sex with them (you literally need to, because this is the only way to get mana) it actually makes me feel something in my stony heart. Considering that its 100% text, that's saying something.
This goes even further because the scripted characters (with plot significance) all have various quests, and you can eventually recruit them to your cause (in some cases as your slave). Since these girls actually have a personality expressed via their plotlines, they feel more fleshed out and consequently more meaningful than a simple whore. I havent even had sex with Emily yet, because I sincerely wanted it to be special (dont judge me).
For what its worth, it is possible to have favorites in midst of a sea of ladies in this game. And for that reason this game earns a massive thumbs up from me.
Conclusion
I'd have to recommend this, but only to players looking for a game with more meaning to their H than the standard. This is not a game if you're looking for a quick fix, even experienced players would need at least 10 hours and for beginners its likely double that to finish the game.
Had this game have a more fleshed out H gameplay, it might actually be the best management H game Ive played in many, many years, and I can't imagine anything even close. But much like the many H management games out there, they all come with issues of their own, preventing them from reaching the top. And this one, bizarrely, is its barebone H gameplay.
Still, if you have some extra cash, I'd happily recommend that you support this game. Just remember to download that art pack for more added fun, or the scripted characters would be the only girls you'll be seeing.
