Yeah, and statistically speaking, didn't someone point out that futa was like 14% of the characters or some low-ish number like that?
The problem with futa IMO, and the reason it gets so blown out of proportion by people who dislike it, is the "trap" factor. Players will already start forming their opinion on characters just by looking at them, and it's a real letdown when what looks to you like an attractive woman ends up having a dick (if you're not into that), so it sticks with you longer.
Hell, on rare occasions the writers intentionally mislead the player, or bank on the fact that the player might be making looser decisions about who they fuck (because it's a porn game), in the hopes of going "gotcha", or "judging" the player on their behaviour (e.g. Evelyn in CoC2, Nayna in TiTS), which IMO just feels like trolling, and does not help the situation.
I don't have the poll, but the story is this: some time back, I asked on the Fenoxo forums about the option to de-dick some futa chartacters in TiTS, and Savin replied to me by saying that they wouldn't do it, because (in addition to technical difficulties relating to how sex scenes are constructed) they had polled their patrons and futa was in the top 3 most popular fetishes. Now, CoC2 might not have the exact same fanbase as TiTS, but I figured that there would be enough similarity to assume that futa must be in a similarly high position among the general fanbase.
