Has anyone seen or tried The Game Crafter? Seems to be an independent game production company who've opened up their printing and packaging services to the wider world, offering to sell people's games print-on-demand - a kind of Cafepress for games. You calculate a base production cost, add whatever you want, and split the difference 50/50 with Game Crafter.
Plugging in Ninja Showdown (three decks of cards, two boards, 25 pawns and instructions) gives an estimated base cost of $14. It's probably not worth it for preliminary prototyping, but might be good for getting a few higher-quality versions built to take along to gaming events. And it's probably as good a way as any to get your game out into the world, if you aren't in it for the money. What do people reckon?
