In-and-of itself, I don't think starting with 1-3 people for a Kickstarter launch is a deal-breaker; the problem comes when you aim for a seven-digit goal with a crew that small, to a backdrop of poor (or virtually
no) marketing out of the gate.
True that they aren't showing much of the team ahead of time though, and that possible recruitment failure is an added risk.
The star power on this KS isn't enough to sell a vague collection of assurances, but I would think that Henkel and Hallford combined actually
would be enough of a driving force to be able to hire some affordable and talented help; I don't think recruitment failure would be much of a risk. There's a lot of talent in the biz that nobody has heard of, who would love to work relatively cheap just to be able have a successful project, created with notable industry names at the helm, under their belt.
Really, I think they're just screwing up two factors: The pitch, and the timing. The former may not necessarily be an easy fix, but its a simple one; just provide a coherent outline, and appealing details, preferably with some sort of audio/visual element, and no DragonBall-Z characters.
The latter is so simple that its actually a little troubling that they didn't have the common sense to do this from the get-go; the past several months have been Kickstartalicious as far as PC games go, and we're about at the "holiday season" now, so why not wait until late January to fire this up?
