This is what side projects are for—except the industry doesn't really give you much time for those.
I can second coding being a major pain in the ass, too. I'm actually working towards my degree in computer science, which has pushed me through one hell of an emotional rollercoaster. I'm close to punching a hole in my computer screen. But I hope it's worth it...
I actually hope to get into game programming, and I can tell you guys it's all about marketing. You can't exactly market a zoo porn game unless you're part of the market... That's why everything out there is low-quality compared to what some of you are looking for. You're just not gonna get AAA quality on any porn game, much less a zoo porn game, because it's only doable if you have money to burn. Which sucks, because I want something good to play too!
That's entirely understandable. Like it or not (for all of us, not a personal thing), love doesn't pay the bills. And sure, we might love our projects with all our hearts but programming especially is to stressful to do huge projects for free. Those kind of work need a reward of some kind. However, I do admit that all the money I saved in videogames will be spent on a bestiality game that has male human on feral animal stuff.
Personally? My ideal bestiality game would be graphically similar to pokemon rangers (the second iteration) and the animations would be in pixel art style. No issue if it is looped and you get different options to engage in sex. Of course, something I would love is the bonding aspect. Growing a bond with an animal and it might have its perks if you're loyal to it.
If I had any patience for coding I'd make an erotic pokemon game where you could opt out from the whole bestiality sex part if you don't want it.
It'd also let you choose to penetrate, be penetrated, and let you choose if you're male, cuntboy, female, or futa (again, the intersex characters would be locked behind the opt out mechanism). Of course, the game would have to be with different creatures because Nintendo will he up for my ass XD.
However, I don't code, I don't like it but I respect those who can deal with it (programmers rock!). In short: I would just like any game that lets my character bond with a female animal and fuck her XD
