Add “Empty” and “Dutch Apple” to the list of flavors of pie.

In the rule “Pies”, after “Bakers starts with zero of each flavor of pie by default.” add “When a Baker joins the dynasty for the first time, they gain a number of Empty Pies equal to the minimum Total number of pies held by any other Baker”

Create a rule called “Upgrades” and give it the following text

As a daily action, a baker may pick one of the Upgrades listed below and perform it. When a baker performs an upgrade, they must first spend all of the Input Pies listed for the Upgrade (if any exist) and then (provided they were able to spend the required Input Pies) they receive all of the Output Pies for the chosen Upgrade.

The possible upgrades are as follows:

Input: none. Output: 1 Empty Pie
Input: 1 Empty Pie. Output: 1 Apple Pie
Input: 1 Apple Pie: Output: 1 Dutch Apple Pie

If a Baker does not perform this action during a day, they gain one Empty Pie at the end of that day.

If this proposal: http://blognomic.com/archive/food_fight1/ passes, add “Input: 1 Empty Pie. Output: 1 Cream Pie” to the list of Upgrades.
