I didn't dismiss your recommendation, I welcomed them, but looking at them, I am not yet convinced. As in many other cases where I am unsure, I call upon other interested parties to weigh in. This case is no different. I had input regarding Confined with Goddesses from others too, they don't seem to match, so I am left confused. I even asked in the thread, the dev's response indicated that femdom only features is his own very vanilla interpretation. Which in my opinion is an oxymoron.
Even if I try to be as inclusive as possible, I have a minimum standard, and I even stated that in the intro on the OP, namely, that I won't consider all games with the tag, which do not or very marginally contains the genre.
Most people are hostile towards the genre and consider even a slightly assertive woman to be a sexually dominant one, which is ridiculous even in terms of "soft" femdom. Most of those people do not have the kink, so their opinion is biased from that perspective.
As for the Succubus game, I asked you specifically if that is the game which I linked above. I saw there were two of them, but you didn't specify it exactly. The one I did looked at, apparently the sequel does not seem to contain any femdom, based on that I assumed the first one is similar. Maybe its not. We'll see.
In cases which are not immediately obvious, I need more than one voice to decide. Cheers!
