Care to state which VNs you consider the greatest? *Puts on weeaboo hat
* Looking at the top list at vndb (http://vndb.org/v/all?q=;fil=tagspoil-0;o=d;s=rating
), the majority of the western audience predominantly considers the greatest titles to be those produced by big companies like Key and Nitro+ -- hardly a couple of kids in their basements. Higurashi and Umineko are doujin titles, but they were hardly slapped together over a summer holiday.
As far as western VNs go, the most popular is probably Katawa Shoujo, and that took literally years to make. And even as a finished product, it can hardly be considered even remotely in the same league as MLA or CrossChannel. Other western VNs made by a basement dwellers are invariably bad. It's also worth noting that doujin software tends to have more salability in Japan than indie software has had in the west until recently (though this seems to be changing for the better).
While I doubt the megatokyo vn is going be all that great, I can understand the need for financial support if it's going to have a hope of being anywhere half-decent. I chucked the guy my $10 and wish him well -- not because I am particularly hopeful of this specific title, but because I think it's nice that the medium gets some exposure apart from the lolcartoonporn kind.
