I wonder what the average schlong length of dick-wielding NPCs is.
Personally, I can hype up the hypersizes so long as they're acknowledged as a fetish. If they're unique, if they require Anusoft or other drugs to take, if they cause legitimate distress for the user (Kiro, Bizzy, the Raskvel Broodmother, etc.), and so on. In those cases, I can correlate hypersexed genitals with the hypersexual reality that is TiTS. They set the mood of the sexually-blessed wasteland that is the TiTS universe.
I do agree that my enjoyment doesn't extend to the sheer number of cum bazookas in the game currently. It's difficult to think of many NPCs with dicks smaller than seven inches - and in real life, I wouldn't want to take a dick longer than seven inches! Some of TiTS and CoC2's charm extends from their meshing of odd fetishes with surprisingly realistic and lovable characters. Many of those non-combat characters have more realistic proportions - Ardia, Liamme, Syri, etc. - but even then 'realistic' means 'under nine inches'. It's usually the combat characters that have strangely massive proportions.
More experienced players could tell me if this is unfair, but I would pin the perceived overflow of oversized peckers on Adjatha's art, especially his newer art. He just... well, he draws big. Look at Kaska's bust - is that a seven inch dick? Anyxine - is that a twelve inch dick? Why are her balls massive? He does the same for other body parts. Vaginas are pumped, hips are widened, abs are ab-ier. Even on a less busty bust like Green's (though her pair still seems larger than the written C cup), the abs are rock-hard and the vagina puffs out several inches. I don't think the writing in TiTS is nearly so hyper as the art shows. (This is a constructive critique on Adjatha's artistic direction; I don't mean to discredit his artistic skill or his massive contribution toward the game.)
At the end of the day, though, yes - TiTS and CoC2 are games best played by people who might consider purchasing a Bad Dragon dildo. The polls I've seen show that the majority of TiTS and CoC2 players prefer dicks of well above average proportion, on them and off them.
