Another AGS game I (and a lot of other people) have been keeping an eye on is VinceTwelve's Resonance. Interestingly, he's used KickStarter in order to fund its entry to the IGF competition. So positive has been the response that he's actually been pledged over ten times the required amount.
As Resonance is being keenly followed by a lot of adventure game adificionados, this is entirely understandable. The XAGE project is still rather low-key, and will remain so until v1.0 and T4W hopefully begin to raise its profile. Seeing that people have pledged both $250 and $500 in order to be included as a character in Resonance only confirms that not only are people very excited about this game but they are also willing to part with large sums of money in order to feel involved in its construction.
My idea: A KickStarter project to allow a single individual to pay a reasonable sum (say, $500 to $1000) to have a short XAGE game created for or about them. Just as some people are crazy for adventure games, a whole lot more are crazy for their Xbox, investing a huge amount of time and money in their hobby. It's not beyond the realms of possibility that someone would be interested in funding some such ego project in order to see their idea or character come to life on their console of choice. It would also tie in nicely with an idea I have for an episodic adventure game on XBLIG, where with each release the episode's financial backer stars as the antagonist.
Finally, Pixel Man was released to XBLIG recently - something about it appeals to me on a very basic level. The tiny graphics, 8bit sounds, rainbow menus and absolutely minimalist gameplay stir some childhood yearning for the Sinclair Spectrum. I'd love to have a crack at making something similar. Maybe when things aren't so busy.
