It's a fairly common theme we see around here, and I think Star Citizen is going to be an interesting case study in how huge croud funding campaigns finish. SC is huge - easily in the AAA game category in scope, detail, and functionality. But it also has AAA funding. But unlike a normal studio, this had to ramped up from Indie to AAA in logistics, staffing, and more. My suspicion is that we're going to see that a lot of delay came from the complexity of the screaming ramp up from small to huge.
That, and, well, I've been served well by patience in the past, and nothing I see about SC looks like it's going to be vaporware. It's certainly never going to be an 'unmitigated disaster', since the game is certainly starting to exist and is pretty gorgeous; at the least, it's going to be a mitigated disaster, which beats a couple Kickstarters for me :)
(Final disclaimer: All that said, all I have for my ship is a bit of wallpaper art; I'd really like to be able to even see my ship, but ... it's going to be a while, and I'd really like to just see it right.)
