Meh, let's just rant about transformative art then.
> I don't think beating UAB be impossible.
I'm pretty sure it's impossible through any platform of "tumblr guy with patreon".
>This OP wants to make possible a crowdfunding to develop their ideas, but they have to sacrifice their freedom, maybe they can offer something different that their public appreciate, but in my opinion I don't find this VN appealing… … and Steam sucks.
Correct, but there's more to it. The problem with UAB is that it's one of a kind, the sort of thing people accomplish in their prime - when they're the most creative, yet also the most depressed, often on the fringes of society - so they cling to their project and spend immense amounts of time on it. That's what berndsoft folks were like. At that point, it's not about the money, not even time, but in kc lingo, 'the settis'. The self-doubt that what you're doing is bullshit and nobody will like it (as most of other things in your life) is what makes you underpromise, and overdeliver. Faggots on steam, patreon and indiegogo can't compare, as those platforms are designed to cater to arrogant deadbeats who usually overpromise and deliver bullshit. Not always, but often enough.
Yet those being mass-media, it's how you can reach audiences - newfags are still important. If this recruits more people into the fandom, beyond what UAB did, I'm all for it, no matter how cancerous it inherently is and even if it's just a trickle.
>UAB is even a critique about that western actual way to see pedophilia.
As for the "muh social commentary" angle … I think that part of UAB is overrated. I frequented kc back then and it's more like reflection of the general hivemind of /b over there. Yes, german /b is very, very into anti-feminism and pedo, some as a meme, some for real. To chantard krauts and to people familiar with german politics (I live close to border), the game was especially precious.
If you're an american, imagine a game made with central plot around milo, brianna wu, anita sarkeesian, kenye west, oprah, kotaku, soros, fbianon, pewdiepie & edgy youtube pals, gamergate, trump, reddit, clinton and /pol. That's what UAB is, but for germany. The writing is not that stellar on its own, as it more or less just cribbed the real discussions and related memes of events discussed on kc/b/ between 2011-2013, which makes chantards identify with it but thats all.
But objectively, the merit of UAB is mostly from VN design standpoint as well as characterization - the lewd art and OST are aiming not technical accomplishment, but for simple and catchy in the tradition of western looney tunes. It works, together it all feels quite alive. The stale /b meme cover on top of it is more or less filler, as evidenced that people didn't give a shit about not understanding half the german memes.
Many people in loli fandom can attest the title of 'gateway drug' is not actually a joke - in more liberal world, if studies on UAB were done, it could prove that lolicon is often a learned fetish, paraphilia like many other. And assuming that sexual orientation is inborn, it means that ton of loli fans are not even remotely pedo. All of this just because the gameplay and characterization has actual depth, not just pressing spacebar for hours like in katawa shoujo. It went to counter everything that often sucks about hentai VNs, even though it sacrificed a lot of replay value for that in the process.
Beating all of the above is not going to be easy, trying to topple something that drastically changed perspective of a lot of folks - the true purpose of art. For "UAB2" VN, it will most likely take different person, but in similiar secluded settis fuchur was in during 2011-12. Thus the result will be most likely far removed from UAB in terms of style and impact. It could be even completely different target group ostracized in current society. Yet very close in terms of spirit and social mechanic. I'm honestly quite surprised there's no famous MLP eroge just yet, though I hear they have more grandiose plans and aim straight for the mainstream (Fallout: Equestria) rather than just weebs.
