I don’t know what gave you the impression I’m especially fond of traditional pre-orders either. It makes more sense when there are actual quantity limits as with physical products than with, say, video games.
It isn’t the same, though. Kickstarter is a different system with different systems of incentives. If you pre-order Pandemic: Legacy you get a guaranteed copy. If you Kickstart Scythe you get bonus content at a discount. There’s also a distinct difference in pressure; in one case the game gets made either way, in another case the game may or may not be made depending on how soon you back and how many other people have already backed. There are practical differences. If these seem scant, it’s worth considering the differences of frequent practice that don’t have to be true just based on the nature of crowd funding because there are differences there as well.
So I don’t like saying it’s the same, because it isn’t. I’m not trying to argue Kickstarter is a radically different space at all, though. That it has problems doesn’t mean those problems are necessarily unique. The character of those problems changes under different contexts though. FFG does not do most of their business through pre-orders and they tend to provide robust post-purchase support for their games. Many Kickstarter projects do not have these advantages. A company like IB&C relies primarily on pre-sales for their success and this creates a cycle where their entire business model is dependent on getting money from people for games that don’t exist yet. While pre-orders have a host of benefits for FFG, they are not FFG’s primary way of making money. At least, not consumer pre-orders. Retail is a more complicated system that once again changes the context of the advantages and disadvantages of pre-orders.
Also, 18 of the 26 Stretch Goals listed on the Kickstarter page for Scythe are for additional components, not upgrades. Many of these are small additions and all of them were apparently considered and prepared in advance of being proposed–this is about as well as this sort of thing can be done but it is very much being done and I’m not sure why denying that is your angle here. This really isn’t very important to me, but I’m confused as to why this keeps coming up in discussions about Scythe’s Kickstarter when it is not factually accurate.
