Tercio Creativo wants to get their 1650 rulebook out to you, the masses, and have started an IndieGoGo campaign with which to fund it.
From the campaign:
After thinking about this for a long time, finally today we can say that the crowdfunding of 1650 for getting the funding for printing the rulebook, with more than 120 pages and IN COLOUR, has started. Stay tuned, because we’ll throw ourself into this. Rulebook won’t be the only thing we will do, if we get the goal ;]
