What's offensive?In fact, I consider this game one of the best on this portal (top 10). But the sex scenes in it are completely worthless because of one blunder of the authors about the size of the penis. And this is very offensive, even with its high level of graphics and excellent storytelling.
The authors have 2 options:
1) leave everything as it is and do further unnecessary sex scenes
2) remake a half-size penis (even this will be enough for the eyes without altering the plot)
The second option is more difficult psychologically, of course. But don't drive this dregs further.
Every female in the game pretty much has proportions and "perkiness" that's just about as unfathomable as the big wang. It's in no way different to every comic book out there, where everyone has more muscles popping out of their body than exist in human anatomy -- it's somewhere between fantasy and genre trope.
I don't go in for most of the hentai stuff because the style just isn't my jam -- I don't consider it worthless or offensive, it just isn't my taste. Likewise for most of the monster/zombie stuff. If hyperbolic big wangs aren't your deal, then the game just isn't catering to your taste.
I think most here would agree it doesn't bother them.
