Sorry that's a long read....but I am just frustrated that Kickstarter is even need when publishers have the resources and could accomplish all of this themselves.
This is a vastly more complicated issue than 'having the resources'. Many (all?) of them are beholden to stockholders, and that means meeting quarterly projections, growing profits, and making blockbusters that sell enough to keep momentum going.
If a small side project breaks even or makes a small profit, it doesn't make enough of a blip to be worth the time invested from the publisher to oversee the project in the first place (project oversight, QA, marketing, distribution, etc)
Basically: They aren't structured
to handle this process, they're structured to make really big games
The industry is diversifying itself thanks to digitial distribution, and we're seeing more games funded directly by fans, Kickstarter is simply another evolution in a process that has already been occuring for several years now.
Make no mistake though, they're paying lots of attention to the Minecrafts of the world, but consider that even if they wanted to, say, spin off a 'mini publisher' that funds digital distribution projects, gamers are fickle, and investing in the wrong ones could easily sink the company, whereas with the crowdsourcing model, the risk is distributed - each of us gets 'burned' to a small degree, which is different than the company going under.
The people who invest/donate/contribute/fund/however you want to look at it are naturally going to grow increasingly savvy when it comes to putting money down for projects that look shady.
Unless we see a situation where shitloads of crowdsourced games fail miserably or run off with the money, it's not going to stop, and that's a good thing.
And really, going by the history of indie games I've funded during alpha/pre-production, I'm completely comfortable with the model. So are many other people who have funded real, physical objects created by strangers online.
Distributed loans are already a Thing too, though I've not done the research into microloans and the like, I don't know how successful they have been.
