http://www.kickstarter.com/projects/992086117/warrior-military-themed-deck-of-playing-cardsA trio of military-themed decks made by a soldier which can also be used to play a collectible card game (a bit like Magic: the Gathering or Yu-Gi-Oh! but with sergeants and artillery).
They're not the prettiest cards you've ever seen, but I have to say I'm curious about this one. What I find most interesting is the minimal list of rewards - aside from the decks, there's a poker chip and some themed bottle openers, and that's it. No uncuts, no t-shirts, etc. It's kind of refreshing to see a deck project that doesn't look like a yard sale!
