The whole thing with lust fluctuation in CoC1 and TiTS has something to do with how those games have/had a minimum horniness requirement to initiate any sex scene, which may be more realistic but it's also kind of annoying if you want to see something and are just a couple points short. Since CoC2 did away with that entirely, there's no real reason to have Resolve regularly decreasing over time. Well, unless you're poor Ryn and have a whole mechanic based around being unable to take care of your perma-horni on your own.
Well, the problem is, of course, then that the condition cited by Savin above, "If her Resolve gets low enough while you're exploring," is not going to be particularly frequent for many players, especially when playing on easier difficulty levels. In fact, it may not trigger at all. As for being annoying if you can't do something because you're just short a few points, it's not like CoC doesn't give you ample opportunity to do whatever it was some other time.
That said, there may be some more content along similar thematic lines in the future. It's been strongly hinted that corrupted minotaurs might get you addicted to cum for example.
Meh. Yes, that was fun in CoC, but lifting things directly 1-to-1 isn't precisely the pinnacle of originality, either. Given all the shenanigans the cult does, I would have more expected that feature to be applied to centaurs.
Forcing players to have sex with an NPC they might not be interested in sexing with no way out (outside the context of losing a fight) isn't likely to ever happen.
Well, the game IS CORRUPTION of Champions 2, no? In any case, a menu option might be added to disable that feature.
