If you back Sandy Peterson's newest kickstarter- Theomachy https://www.kickstarter.com/projects/1816687860/theomachy , at 200 you can get both Cthulhu Wars and both sets of Theomachy. Currently, each set of Theomachy is at a $35 tier, with a $50 MSRP... So essentially, $300 MSRP at $200.
I'm not sure how I feel about Theomachy, but you basically get it for free- can sell or trade it if you aren't happy with it. Definitely beats $450 on amazon.
