Kickstarters certainly are going through growing pains, and it's the runaway successes that really seem to crash and burn. I have no idea how Reaper managed to deal with their KS. Stretch goals and freebies up the $$$ but that stuff really seems to cut into profit in the end.
One KS that seems to have done really well was the NeoLucida, an art device. When they launched it, they straight up limited the pledges, once they were taken, they were done. They had budgeted for a certain size production run and stuck with it. Now they can be had on Amazon, not long after the KS funded.
Companies really need to set a goal and stick to it, forget stretches, freebies, etc. get the funds, make the product, keep happy customers.
Red Box makes sweet figures, but I wasn't the only person wondering why he was going with KS.
