Ehhhh.
It's doing relatively well right now for sure. But, it reached it's peak years ago. At least according to graphtreon.
It's been a slow but steady downward trend from that point onward. Mind you nothing they'll ever have to worry about unless they plan for CoC2 alone to carry them for decades (they don't). Wouldn't be smart either at any rate. From it's peak it's been a near 500 drop a year. While half of that could likely be attributed to Patreon's big oopsie that required a bunch of people to resub to their subs, that's only for that year.
Who knows what makes people unsubscribe. But they do. Nothing lasts forever.
...Except Summertime Saga. Better than ever (financially). Ain't that just something.
I am curious what they think.
I was curious enough to check it out. Not my cup of tea. There are authors in the porn game space that can write scenes with enough finesse that I can enjoy them despite them being out of my usual comfort zone. This isn't one of them. But for me, I'm "pretty" sure the difference is the (lack of) after care. Or maybe it's a whole bunch of different reasons, it's hard to accurately and adequately parse why I like something sometimes. What I'm trying to say is, Xotchi in TiTS has no sex at all. I'm generally comically repulsed by pain play. However, the aftercare afterwards was done in such a way that I liked the NPC and grew to not mind the scenes.
But, I'll say from a less abstract stance, every scene ending with practically a "and then they continued fucking" with a follow up flash forward is a bit weak.
I would imagine modding a game that updates at this frequency isn't very appealing for one.
There was a mod years ago. It was discontinued not due to difficulty (it implemented Drifa nearly half a year before CoC2 proper did). It was discontinued due to lack of interest.
