I woke up today and checked Kickstarter to see the games that were listed, and I see slowly, but surely, that Zombicide keeps dropping down the list and away from the public eye. I'm not sure, but I think the position of the games, with the ones at the top being the most desired, is indicative of the amount of money they earn over a period of time, not their grand total. As such, since Zombicide's pledges have started to slow down other (i.e. newer) games have pushed it farther and farther down the list. The exception to this is Machine of Death.
Machine of Death has managed to stay pretty much near the top for its entire Kickstarter campaign, and I think teh reason is simple, they're running a very exciting campaign. At one point I considered pledging for their game, but changed my mind when I realized that with only 2 players playing Machine of Death between us wouldn't be that fun. Even so I hate it, because their campaign really keeps on piling on all these goodies!
Now I'm sure the common argument here is, "Well yeah, they can do that because all they're giving out is free cards, Zombicide is giving away miniatures". But that's just it, we've had $20-40K stretch goals for 1-4 miniatures, which is fine, but we don't need stretch goals to be miniatures. Do I need another Abomination? Hell no. But what about cards? I really think it would be great if GG considered adding free new cards to the games as stretch goals.
As I've expressed in other threads/posts, miniatures should come with a unique card. An easy example would be "Ralph" (i.e. Tallahassee) should come with the item card "Twinkie" (or fearing copywrite laws, "Snack Food"... and just make it look like a Twinkie). If GG did something like this, which would be unexpected, I would know it wasn't planned as always being a part of their campaign and the bonus cards wouldn't take up as much room in the box. They could start with free cards for the optional purchase survivors, then set another stretch goal for the free promos survivors, then finally move to the survivors who come with each box set.
Anyway, that's my thought on the matter. I truly miss the first 1-2 days of the Kickstarter campaign when stretch goals and "freebies" were coming our way at break neck speeds, and while I can understand that GG can't give away tons of miniatures they do have other options that can be just as rewarding to players.
