Players receive no more 5 free MP for modern era to leverage paying fuel.

Rulebook has been split in two parts: Rules and Addendum. The Rules part will discuss only about rules and examples, while the addendum will contain only hints, strategies, etc.

Added priority rules to determine barbarians movements.

Three new examples have been added to the barbarians chapter to ease the understanding of new rules.

Better look for every reference card.

Barbarians reference card added.

Hostile fleets are now aware of adjacent sea spaces and can join to other hostile fleets or attack nearby player fleets

Coastal regions with barbarians settlement can now spawn hostile fleets

Barbarians can now take advantage of abandoned roads and railroads

If there is more than one hostile attacker on the map, you are required to determine a random order of play of all barbarians

Hostile attackers will move or not depending on a random factor. In this way there can be a possibility for barbarians to pile in greater armies to have some more chances against human players

Barbarians can now occupy a player settlement (includes pillaging). If they are enough units, as time passes, they can overwhelm the occupied settlement. Once it is caught they will attack with more units nearest settlements too

Players fighting against barbarians will battle against them by means of the first player in turn that will impersonate barbarians for dice rolling and unit selection purposes

An option to make bidding more challenging has been introduced. Secret vs public bid (Michel Keijzers)

Added a new event score column for the Modern era that differs from the one of the Industrial era

Catapults are no more automatically upgraded to trebuchets. You have to purchase trebuchets or upgrade catapults as any other unit

Permanent gold rewards of strategy cards do not expire when era changes. Stop taking the gold reward only if the conditions of the card are satisfied no more

Every card now has a symbol to immediately identify its type and remove some possible ambiguities

Two new cards have been added to give a +1 bonus if you attack with particular unit types

The sentence “Draw another card” on some cards has been replaced with a symbol

The reward for the objective card “Destroy a village” has been lowered from 50 to 30 gold

The two “clear jungle” cards have been eliminated. Their effect is always available with terraforming

The war weariness rule states that the winner must eventually choose which improvement to eliminate if the loser has not enough gold to afford the loss. This rule has one flaw if the player loses against two players in the same turn because they will be in competition choosing which improvements to eliminate. The revised version of the rule gives the choice to the loser

When you pillage and destroy a settlement you get 10 gold multiplied its size from the bank; when you convert an enemy unit you can destroy it and get immediately half of his value from the bank (Guido Heinecke)

If you terraform a region with a settlement it will be destroyed: leaving it there is quite unlikely!

The physical exchange of two resources now is easier: it will use only two flag bearers instead of four, fills less space on the table and it is easier

Added a new chapter “Errata corrige” to include in the rules the official Eagle Games errata for the cards contained in the original game box

The mini-monopoly rule has been removed because it adds small advantages compared to the complexity it introduces

During production phase giving back traded resources it is no more necessary.
If two players have traded resources and then they go to war between themselves, resources are immediately returned to the original owners and the trading is canceled.
If the enabling conditions are unsatisfied at any time during the game, resources are immediately returned to the original owners and the trading is canceled.
A player receiving an oil resource can immediately use it to increment his free movement limit during the Modern era (conversely who gives away his resource decreases his free movement limit)

Counting units for movement during Modern era has been simplified: count how many MP you use for any unit instead of modern units only and about how many of them you move

New variant for expert players to increase the strategy factor when planning attacks or defenses: resolve battles after ALL players have finished moving

Modern units movement dependency by oil has been modified to create more competition between players for oil resources. Players with oil resources will earn gold from other players' movements in relationship to how many oil resources they own.

The pieces limit rule has been revised to include a variant to allow unlimited pieces to players who do not like to be restricted in any way

Strategy cards have been unified between Standard cards and CHR cards: strategy cards rules have been then lightly simplified

Spies can NEVER act during the Housekeeping phase
