I appreciate the lengthy post, as well the the other one you linked to. They were interesting reads, and more than anything it's always nice to see people that take an active interest in the future of visual novels. That said, I don't see social games as offering any kind of salvation to the limbo VNs have found themselves in. And it has little to do with the people making them, but rather what they are at their essence. They exist for only one reason, to suck away as much money from players as possible and to get you addicted. It's very much money first, art second. And while this is the general rule for all artistic mediums, the individual works of art that stand out as great, often are lead by those insane people who are motivated by the opposite, art first and money second.
Now this is where my point of view radically deviates from most, so I don't expect many to agree with me. What interests me about VNs, is the artistic medium itself. What can be done with it, and how it can express themes, stories, and philosophies uniquely from other mediums. In that sense, even if VNs became massively popular. If the only things we are getting are commercial titles that appeal to the lowest common denominator (like typical Hollywood movies), I really don't care for the medium to succeed. Often when an industry is relatively new and going through it's boom period, people are more willing to fund experimental works; which is where the creative and imo interesting stuff comes from. And perhaps it's my own biases of what I've seen social games as up to this point, but I have a really hard time picturing anything deep and interesting coming out of a genre that is just glorified gambling.
One of your key arguments is that these upcoming social games will have massive scripts. That's great for people who are addicted, but that is no guarantee of quality for people with critical eyes. "Bigger is not always better", and "quality over quantity" exist as phrases for a reason.
Regardless, this is just my two cents. And I'm what is known as a bit of a curmudgeon. And despite my cynicism, I really meant what I said in the beginning. Above all else, it's nice to see that there are people who still care about the future of VNs. So long as there are people who still care, the medium still has life in it.
