I think there's a lot of things at play when it comes to futas/dickgirls/whatever other names there are, in games. Besides it growing as a fetish, I think it's just the next level. If you look at porn from the 70s it's completely different then the porn out today. How many girls were getting double fisted in their pussies while chugging a beer with their ass and singing the national anthem during the 70s? Not sure if that's a real thing but in this day and age it's certainly plausible. Now that it's been said it's even more likely to actually happen. Point being as we become more used to something we become desensitized to it and move onto the next thing. As adults with internet I think we can all agree we've seen some shit. Compared to when we first got online though how shocked or appalled are we today? Unless this IS your first day on the internet in which case welcome, it's all downhill from here.
I think as the fetish grows and people become more okay with it the games are starting to show more and more but also the fetish has existed for a while already and there were hardly any games. We live in a time where decent hardware is affordable and there's plenty of resources for people to make their own games. Anyone with internet, a decent computer, and some cash to buy assets or the time to download them from some site can make a game and I think that's what's happening. People who've been wanting a certain something in a game haven't gotten what they wanted so they're now making their own games and finding like minded people.
I'm one of those people. In that I've started making my own game. I built a new computer, and purchased a ton of DAZ assets. Now I'm not into the whole futa thing myself. I like where most games are right now. In these games I do enjoy a well written incest story, or just a good story of a good MC finger blasting every girl he can get his hands on. I'm a simple man. However as someone who wants to please people and offer up as many options as I can manage and satisfy as many fetishes as possible. I personally find a true futa to be very appealing. A true futa for me being a woman with a cock and a pussy but no balls. HOWEVER I would make it optional. I'd like to keep the character going but to be able to cancel off any sexual options with her. I'm still working it all out but to make the character I want to make I feel the best option is to make her a futa. It'll allow for some hot threesome action that'll lead to the true ending for that characters story but I'm also contemplating putting in an option for the character to have the penis removed which would allow the character to continue as a romance option but would cause a huge drop in content for that character.
I'm sure I'm not the only person who's felt this way. My goal is to make a game that pleases me but also pleases the players. Something where everyone can find something they want. I think it's important though, for now, to keep things optional. Things like NTR, futas, bestiality, and pregnancy. Personally though, even though I'm not that into futas I just see it was a more convenient strap on. We're all good with lesbian porn where a woman gets a strap on and actually fucks the girl. I usually just skip ahead to that part cause let's be honest. Scissoring is total fake bullshit. There could be a foot of space between them and they'd still be moaning. Just pretend she's wearing a lifelike dildo though and it changes your whole view. I don't like seeing sweaty guys fucking these porn babes. I do like seeing a sexy girl fuck an equally sexy girl with a strap on though.
