Kickstarter has been used quite a lot by a whole bunch of artists to deliver comic books; if you look at money brought in, it's consistently ranged from being the #2-5 publisher of comics in the US.
While some of these comics were done on the "here's a pitch and my track record, pay me for a year's work in advance and I'll make this" model that the Double Fine adventure is being made on, the vast majority of them were not - most of them are about "here's some stuff I already drew, I need this much in preorders to make a print run economical." This goes all the way from little campaigns like the one I ran[1] up to huge ones like the $1250k one for the Order of the Stick reprints[2]. Kickstarter has helped make independent comics a lot easier to sell. It's also been a huge boon to board game makers, who work in a similar "make the thing, then seek money to publish it" model.
It is quite possible to run a successful Kickstarter based solely on delivering the product to the audience, with absolutely none of the glimpse into the creative process that Double Fine is providing.
That said: be aware of what you're getting into, be prepared for it to never happen.
