I've recently discovered the solution to 3 hidden recipes in the Zombie Slayer workshop. The workshop can be a lot of work, discovering secret recipes moreso. I would suggest: Awards for 1, 10, 25, 50 different items built at the workshop. (5 favor points each.) Awards for 1, 5, 10 different hidden recipes built at the workshop (10 favor point each.) Award for being the discoverer of a hidden recipe; 25 favor points to a player that is the first in the game to discover a recipe. They need not share the method if they don't want to.
