I supported, then backed out of the first two kickstarter Pinball Arcade Campaigns. Usually with Kickstarter most give some sort of incentive to support their project, and not have the same benefits and pay more. Sure you're making sure they get the funding they need. But with a Stern partnership, and a roadmap already planned out, I'm going to guess Stern and Farsight will not let this fail if they haven't reached their goal by the end.
So while I'm extremely excited about this, I have no worries that it won't meet the goal, so I'll just purchase this when it comes out.
Hell, even if they would throw in a brand new shinny pinball ball, I bet they'd get more interest in support from people. To us, I'm sure we'd shrug our shoulders, but to others who've never actually held a pinball in their hand, they'd eat it up. I know I did they first time I got a pinball that was included in a computer game back in the early 90's. Can't remember what that was called now.
