Monster Girl Quest, Violated Hero, Succubus Prison, Excessm, Lilith Unleashed, Succubus Senki, Shrift, Succubus Covenant, Echidna Wars, Lust Grimm, Yumesame, Echidna Wars...They all embrace my "more dangerous and less moral kinks." The succubus myth going back to Sumerian and Jewish mythology embraces the "more dangerous and less moral kinks." They are demons. But, relax. Nobody is telling you what to do. I'm just offering an opinion.
The other user seems relaxed to me. Personally, I think your original comment is… how to put it in English… misplaced (mind, not wrong).
Over the years many authors have put their own spin on Succubi; there are those who stick close to the myth and others who turn a Succubus into a creature who keeps her "victim" around and gets lovey-dovey with him/her.
That said, Monster Girl Dreams' take on monster girls and succubi isn't off the mark, it establishes fairly soon why things work the way they do in Lucidia. Convenient plot device? Maybe you think of it like that, I don't know, I'd like to add something else… this very page states: "You can also spend time getting immersed in the game's whimsical setting and (usually) upbeat tone," it's clear one isn't going to find the same kind of Succubi experience provided by S.Q.D.T.'s Succubus Academia (example) here. To have the gall to come here and say to the author he/she missed the mark when it's made known the game goes for — and maintains a light tone is amazing in itself.
EDIT:
Addendum. From personal experience, fetishes are a source of a danger, from a gameplay perspective… indulge too much into whatever gets you going down there and you're going to have a hard time avoiding some of the stuff those ladies throw at you (even if over-levelled, throwing this out there, I've beaten the strongest opponent currently available in the game "solo" and she was fighting at full power… can still get screwed over by fetishes). What? The costs for removing those and increased sensitivity aren't steep? Well, way to shorten the grind.
I wouldn't waste my time commenting on the game, unless I thought there were a lot of things that I liked about it. With all the time and energy that you have invested in the game, I don't expect you to change the format now. I don't think there is a right way or a wrong way to construct a game. When I did my movies, I followed my own passions and didn't get caught up in what other people wanted. So, if this is what rings your bell, more power to you. I thought you were taking an unusual approach, so I offered my perspective. Peace.
Hm. I'm not the author of the game, I don't know why you're speaking to me as if I am.
I'm another fan who is merely offering his perspective on things. As far as the unusual approach is concerned, I don't understand how it is unusual when the "Hentaiverse" is loaded, absolutely loaded with works who have their Succubi be sexy, domesticated ladies who deliver amazing sex and merely capture their prey afterwards, if anything, the "I'm going to drain you until I kill you" kind of Succubus is a rare sight to behold. Ratio favours the first type, at least in my experience.
Things with monster girls-focused works could be slightly better, but even in those there are ones who keep their victims alive, going as far as turning them into husband/wife/source of nourishment.
Back to Monster Girl Dreams, I understand it sounds like I'm "white knighting", but again, this homepage is stating just what kind of content one could expect to find in MGD, for those who don't bother to read that stuff, the game itself tells the player how things work as he/she is making the first steps. Well, it seems to be fairly easy to mod, so, nothing is theoretically preventing anyone from creating a more dangerous kind of enemy.
