* Economy

Current primary resources:
- wood				growing/harvesting
- stone				non-growing/non-harvesting
- wheat				growing/harvesting
- algua				growing/harvesting
- fruits x3			growing-on-tree/harvesting-on-tree

New basic resources:
- papyrus			growing/harvesting
- fresh water		underground water table
- salty water		infinity

Future new resources
- healing plants?

New intermediate resources:
- book					to create constructors
- armor					to create melee warriors
- canon ball			for towers
- construction stones	for advanced constructions
- plank					for advanced constructions
- spear 				for ranged warrior
- jam					advanced happiness resource (counts x2)
- bread					richer food (satiation + 50 %)
- tartine				richest food (satiation + 120 %)
- candy					advanced happiness resource (counts x4)
- alcool				for healers
- baloon				for explorer
- rocket piece			to get the hell out of here

New resource creation path
- papyrus + wood => [book, armor] in paper workshop
- stone + water => [canon balls, construction stone] in career
- wood => [plank, spear] in wood shop
- fruit + water => [jam, alcool] in sugar workshop
- wheat + water => bread in bakery
- jam + algua => candy in bakery
- jam + bread => tartine in inn
- algua + payrus => baloon in laboratory
- wood + algua + jam + ... => rocket piece N

Updated resource behaviour
- root allows resources to regrow

* Buildings

New buildings
- well (deplete water table) and provides fresh water
- paper workshop
- career
- wood shop
- sugar workshop
- bakery
- laboratory
- armory		(stores alcool and spear)

* Units

- Branching based tree:
  basic unit --> constructor			in school requires book
             |-> healer					in school requires book
             |-> basic warrior			in school requires book
                 |-> melee warrior		in barracks requires book + armor
                 |-> ranged warrior		in barracks requires book + spear
                 |-> explorer			in barracks requires book + baloon

- Units consuming
  - healer consumes alcool
  - ranged warrior consumes spear
                 
- Behaviour
  - war flag holds a mix of units
                 
* Behaviour change

- warriors consume more food than before
- water table evolves
- inn requires water to provide food
