Actually the furry was just an example (it was the first thing that came to my mind XD) it can be any kind of character that can be well adapted to the HC world (and that doesn't require a lot of work when making their Sprites).In terms of Genre, i'm pretty sure that the Corruption/NTR theme is gonna stay the core of N_Taii's games, so are the pixel graphics if you ask me, but i can see N_Taii making a game that's separate from the Henteria series. I'd love to see a steampunk or even a modern style game but the problem with those is that compared to the medieval setting where it's mostly just nature with the exception of a few houses here and there, a game that's set in a steampunk era has a MUCH denser enviroment, therefore it takes more time to create maps for it, or so i would imagine, after all i've never made maps of any kind.
As for your furry comment...as long as there is corruption and NTR involved i'm pretty much in, but i don't know how i'd feel about spending money on a game that has Furries in it, or i guess i do...so i REALLY hope that N_Taii isn't wired that way.
I'm almost certain that when you said "other types of characters" you meant different species like furries, but i'd rather have N_Taii stick with humans and elves, but next time instead of using the ol' reliable teen MC with the Mom/Sister/Female best friend setup, i'd rather see him make something more...original, i guess. For example a middle aged MC with a wife and 1 or 2 daughters, i guess the Mom/Sister theme could stay as well, but since the mc is a middle aged man here, the mom would be more like a younger grandma and the sister would basically be the middle aged aunt to your daughter(s) with a family of her own.
A Steampunk game would be interesting, but as you say it requires a lot of work for aesthetics and map density; maybe making another game in the modern era like Merry h-mas would be the best option.
In that you are right, there are some projects on Patreon that in theory violate the restrictions of the page and they are still there. In the same way, they deleted accounts that had very good projects and they did follow the rules; so we can conclude that in the end the Patreon restrictions are a joke.I would assume it's probably the latter, because Patreon's restrictions are... wildly inconsistent to say the least. When you have games like The Curse of Pleasure, Claire's Quest, and The Legend of Queen Opala: Origin surviving on there just fine for years despite blatantly violating a good number of those restrictions, I feel like Henteria would have a particularly easy time getting away with it given that pixel sprites endow it with an enormous amount of ambiguity.
But there is still always that risk of Patreon singling one creator out, no matter how unlikely it might be. And to N_taii, that might just not be worth the risk when balanced against the benefits of dipping into those waters. Which is a shame, because I personally would have ~loved~ that being part of Haylen's sidequest — that instead of Jazon as a direct rival to Leto as he currently is in the story, she might have taken in a new orphan in the same way that she originally did with Leto and Cyanna — but it's also a perfectly understandable concern to have when the series has already been so successful.
It's also true that HC is a pixel-based game so maybe it can get rid of some restrictions, but I don't think N_taii wants to take that risk; besides, if I remember correctly one of N_taii's future plans is to distribute HC also on Steam, and that platform also has very strict restrictions on hentai games.
