Empire: Everyone builds their own units and resources but shares both with anyone that needs it (Usually the leader)

Like the one-for-all Strategy everyone produces their own units.

but in Empire, each person fends pretty much for themselves until their Emperor or chosen player needs help to get a medal. that's when you either, declare with that person to assist them in gaining land, or give them your units and resources to make them stronger.

This is good for a pact with a lot of new player, people who aren't always on, or people who get along really well and don't mind helping out just one person for a whole round.
