Really surprised this game does not have a greater following.
Even in its current state it's very stable and playable. It has original and, in my eyes, gorgeous art (really dig that watercolor-styling). It's an actual game with detailed mechanics and a lot of variables to toy around with. Also, obviously, pron.
While the pacing is kind of all over the place (some parts of the game seem to favor months-long gameplay, default duration is around 30 days +/- 10 or so), balance is there, but far from perfect, and there's a lot more art that could be added, it's still a solid entertainment for a few weeks at worst. A lot of the "unique" characters feel more like placeholders (basically of little inherent value save for potential unique trait you'll want to snatch and add to your breeding lines), the "dating" part is pretty rudimentary (and a bit confusing in the way it handles Lewdness increase). The town itself, and "home" upgrades, also seem to be in process of development rather than their final form, but again - all of it is already very much not just playable, but genuinely entertaining, and can be quite challenging while you're still learning the game's mechanics.
On the other hand, the game does come with a lot of built-in help explaining core concepts, which is a huge help.
The sheer amount of tools at your disposal can be overwhelming at first. The three main characters play vastly different (frankly, I've only dabbled with Creation and Prince so far, still trying to figure out all the little things to do with Evolution even after a few weeks of regular playing). On top of that, your roster will not only vary depending on your playstyle (and species) preference, but also availability of the randomly-generated enemies you can "recruit." You can further specialize roles by the choice of equipment you put on the characters in your current party.
While you will not avoid some combat (unless you choose to play Freestyle, anyway), you don't have to pursue battles much and can still advance - though probably not as well as when being combat-oriented. The town itself provides multiple means of generating income and, after initial Portal harvesting, other resources. In fact, getting just two or three decent Brothel candidates can pretty much turn money into a non-issue. There are multiple "home" upgrades that'll do the same for all game resources, as well (pretty sure this part is not final, either - things get too easy rather fast if you know what you're doing).
The core of the game is the attention to individual characters, though. They all have a LOT of various statistics which affect multiple parts of the game, from combat performance, through brothel earning, to being trade-able goods or breeding candidates.
Main characters are even more detailed, in that you have a lot of freedom to shape them in whatever function you prefer. In Evolution's case (the first futa character), this comes with a built-in mechanics for quite literally changing your function (and shape) as necessary at any point, as long as your exhaustion allows, and "point-buy" system that improves the end result as you progress in the game.
I probably should stop gushing, but this is a really, really good actual game. I thought (and, well, still think) Strive for Power was excellent in the whole "farm/breeding/management" genre, but Portals easily takes the crown through its depth alone.
It might be that the old-version screenshots of the first post are turning people away from an excellent tactical and management title, considering how unimpressive they look compared to current visual state of it.
Anyway, definitely recommend trying.
