Oh, come on. 90%+ of all 3D/Hentai content is Vanilla/Other genre. And when someone talented starts to do heavily some specific stuff/fetish, you guys want to ruin fun for all who has to patiently wait for this kind of stuff like... months or even years.
I do get you. It's true it would be shame to not use other "assets" the models possess, but I personally would be glad if main focus would be on foot fetish.
My POV:
I check out loads of games/works, seen tons of great games and artists doing their stuff, not whining in threads that MY type of content is missing, just quietly and patiently carrying on, searching for those rare gems. And finally, when I find something incredible, some people just come and starts "No, don't do that, it's boring, he should do X and Y...".
No, this artist likes this and this is OUR turn. You please move on this time.
