Also I agree with that, though its hard to decide what would make a 'quality' VN. To me, a big factor is art. I dismiss most OEL VN's based on the art, which is shallow of me I understand, but if a group of people on 4chan made a VN with an art style that rivaled some official companies, for free, why can't people backed by crowdfunding work a bit harder in that aspect?
Though I do remember an interesting looking VN on indiegogo, the art looked good enough, and they had a nice little tier where you can add an OC of your, drawn by the artist. Can't remember the name though.
Recently a lot of VN's are being licensed and translated, something I am very glad for, though sucks for ORL VN developers. Although I don't like the artstyle for most VN's I see pop out on an almost weekly basis I would love to see another good OEL.
As for the budget thing there is kickstarter, its worked in a few cases, and yeah include a gameplay aspect. One of my favorite VN's, Kamidori, has a very fun gameplay mechanic. People just need to find the right kind of gameplay that won't be seen as ripping off something else, something that's very hard to do these days.
