Of all the boutique pinball companies to pop up, really the only guys who are doing it right are SkitB and at this point to a lesser extent the guys doing Big Lebowski.
Reason for the is, they didn't come to market with their hands out, or with nothing.
In SkitB's place, when they first started taking deposits they already had a working whitewood that had been out to a few shows for people to see. For me that created confidence because hey at least I know in some capacity they can at least build a machine.
That plus the very low required deposit of $250 made it an easy project to jump on.
Similar to the Big Lebowski, while they are requiring larger deposits then say SkitB, they have already come out with a little bit of actual gameplay footage, and since this isn't going to be only a small run of 200 or less, have given the general populace a chance to sit back, watch and wait to see what come to fruition, meaning you can eventually get a TBL with very little risk.
These guys basically need you to pay for the entire machine up front, have nothing to show in the way of gameplay, no working prototype and a really bad video to try and convince anyone to shell out over 7K to buy their machine. It doesn't fill me with the warm fuzzies that they know what they are doing.
With 0 history behind them, I don't see this kickstarter succeeding, but who knows.
