It's certainly a cool idea and not a huge amount being requested but I think it's inadvisable to put up a Kickstarter at all when you have nothing to show. A text description is good and all but anyone can make it sound like they're passionate developers with strong vision and blah blah blah. It takes a lot more to ship a game. I don't really see this campaign going terribly far unless they can show their potential fans that this isn't just a pipe dream.

(This goes for almost anyone trying to make a Kickstarter. I'm sure this group really does believe in their concept, but that's not enough to be successful.)
