Okay, so my list. It's a long one but I long for a high-quality porn RPG and the ones out currently rarely cut it for me, and I've been hoping to see CoC2 for a long time. So, here it goes!
- An interesting plot with both major and optional quests that are fun to play through. I've had more fun with stopping the planet-cracking pirates in TiTS or trashing Krawitz' mansion than I did when I was just clicking through dozens of cheap sexual encounters in TiTS.
- No walls of text. Larger amounts of text only when it's required.
- Coherent setting. If it's fantasy let it stay fantasy without throwing in random modern-day references (those coffee machines really threw me off in CoC1).
- The ability to skip sex if you don't want it. For the sake of roleplaying heterosexual, homosexual characters.
- Character sexuality? It'd be cool if my gay character wouldn't be aroused by characters of the opposite gender.
- Good, fun, old-school dungeon crawling, especialy optional. "Hey dude, heard there was a handsome dragon prince living at the end of that underground fortress with tons of cool loot to spare and millenia of solitude to *cough* make up for! *cough* "
- Diverse and genuinely well-written characters who are characters first and fetishes second (or third). I have a hard time getting to like a lot of TiTS characters because of that. On the other hand the more I knew Terry in FoE the more I wanted to have sex with him. Another thing: They really don't have ALL to be over-endowed. A character can be attractive without having enormous tits and a dick so huge he/she can use it as a lasso.
- The ability to grow a dick so long you can use it as a lasso.
- Some sex options that you have to earn. Not all, of course, but I always enjoyed developing relationships in CoC and FoE that gradualy turned sexual.
- More furries! I missed them in TiTS.
- Inter-follower sex scenes and romance subplots you can encourage or stop. Inter-follower interactions in general, makes them feel more like characters with their own agenda.
- Party member sex options for encounters? I always enjoyed my fair deal of voyeurism in Fall of Eden.
- Some limits (story limitations, subquests, date/relationship continuation options on few day long cooldowns?) to how fast can you progress with characters. This may seem odd but I never felt happy with how often you'd click through an entire relationship in one day in-game. Let those things grow naturaly through the game.
- Consensual, non-punishing, non-depriving sex. It's nice to see some BDSM/fetish options but it gets boring when every single character wants to walk you through the town naked on a leash.
- Customizable party members? At least to an extent?
- A good variety of m/m, f/f, f/m encounters. I never play heterosexual characters in those games but I noticed it can be damn hard to play a straight male who's not into dickgirls or, even worse, a straight female. It can also be hard to play a straight lesbian.
- Less over-endowed dickgirls. PLEASE.
- Cuntboys! Cuntboy followers! And, of course...
- Mpreg! Not just c-boy, but m/m and f/f (Fpreg?...) impregnation in general (say, a rare magical spell/potion/transformation that turns an anus into a womb or makes female cum impregnate other females/you). It'd be cool to be able to see such content without having to transform into a herm. Of course, this option should be adequately hard to get.
- Incest (Yes I know it's off limits due to Patreon but I CAN DREAM HAROLD!)
- Ability to hire prostitutes (maybe for your followers, too?) and to prostitute yourself.
- Rare transformations from very rare encounters/boss battles/dungeon loot that can give you special powers. Say, a potion that gives you magical draconic horns of infernal power +3, that sort of thing. Kinda' like Ember turning you into a dragon if you wanted to.
- Subtle transformations like glowing eyes/magical horns/mystical tattos et cetera; So you can have physically unique characters without transforming into a different (or completely hybrid) species.
- Tons of weapons, equipment and armor, including jewelry, bracelets, various types and forms of weapons even in the same category with the ability to mix and match the elements to be able to have exactly the character you want. Those games are about expression, after all.
- Interesting class system with rare/special class options (E.g. Paladins, Death Knights, Sexmancers, et cetera)
- Living armors, Goo armors, modifiable, body-tight armors, I have a soft spot for those.
- Lion TF <3
- Vendors and shops where you can purchase cool stuff and not only gather stuff as you go.
---------
In general what I'd enjoy would be, basicaly, a sex-filled fantasy RPG which is first and foremost enjoyable as an RPG that happens to focus on and have lots of sex scenes, and not a random RPG-tinged repository of mismatched sex stories.
