Modern-day Realism(ish)-based, drama porn (like GGGB & ORS):
Dr Amana: "Aboned" unfortunately. But pretty fantastic for a porn vn. Hopefully dev finds a 3d graphic artist to help him compose more scenes, as he has no time for it right now. Download 1.5 FIRST before 2.0 update, as the content is separated in two.
Casting Director: Yes, it's HTML & Real-porn based. But surprisingly great (at least for a porn game). Highly recommend over most modern-day-based VN style porn games.
EraStorm: Magical elements in it. Not fantastic, but decent enough for a porn game (as most are pretty terrible). Palatable enough to play through is all I ask, and this one is.
Couple's Duet of Lust & Love: Great if you like cheating & sharing-themed content. Graphics are strange at the beginning, but dev improves throughout. The "dancing" animations are pretty cringe-worthy though. And I don't like that on certain paths, player has no choice but to accept sex with some characters. Still recommend if cheating is your niche.
Bright Past: Grindy and uneven as fuck, with a few cringe male 3d models, no non-scumbag male love interest. Bugs galore. Implausibly sexual in general, with no choice but level of corruption. (MC is getting corrupted regardless of your choices. Just depends on to what degree). Still. A WHOLE LOT of potential. So many options and the level of depth in developing your character is, for a porn game, pretty astounding.
Long Story Short: Developing slowly but nicely. Ignore the super-cringe fat friend model at the beginning. The model work on that character is awful, but the game gets better and has potential.
The obligatory
Jessica O'Neil: Porn portion is boring as fuck to me. But decent enough writing. Worth a playthrough. Not a game I'm super-excited for updates on, but a good time killer if you're looking for something to blaze through once.
I can add some more cartoony, comedy and/or fantasy-based porn VNs too if you're interested, including some pretty great ones. These were the best off the top of my head for modern-day based games which at least make an attempt at realism though.
On the real, I wouldn't call most or any of these games professional-level, quality writing (except maybe Dr Amana). Though honestly, I'd say the same about Eva's games. Hers are a level or two above most if not all of the games I've listed, however. Videogames are rarely written well in general. Doubly so for porn games. But for those of us with a low tolerance for absolute shit writing, these are all (for the most part) bearable enough to get through and enjoy without abandoning and deleting within the first half hour. That's all I ask for, personally.
