I have no idea what other indie adventures are being released this year, but it would be really cool if an Indie Adventure Christmas bundle could be put together and distributed.
Yeah, you really don't want to release in a bundle, though. It's a really bad idea. You want as many full-price sales as possible at launch, and then run sales or bundles once that tapers off. Watch what Wadjet Eye does; Dave is wicked smart about the "long-tail" nature of his catalog. Primordia has had hardly any sales (for example, having launched 12/2012) but we see the Blackwell games and Gemini Rue on sale quite frequently.
I'd dearly like to see the Humble Bundle guys do a themed bundle, a Humble Adventure Bundle, full of cross-platform graphic adventures, someday. That would be so incredibly cool to me! QFI would fit nicely in that fantasy bundle, I would say, and would help justify the feverish lengths to which we are going in the AGS engine porting community, especially if QFI could be joined by other Kickstarted AGS adventure games (like Stacy's Jack Houston project, Himalaya's project, and maybe Alasdair's Nelly Cootalot sequel, for example).
