Civ Duel Zone - Inter-Site Demo Game!!!

We should all get CDG log ins I guess...

I must say I am seriously impressed by that list of exploits from MZO ! I think I want it applied in all my PBEMs :D

The following is a list of some known exploits. Note that these are not all the exploits, so if an exploit doesn't appear here, it is still illegal. The administator may edit this list as exploits are discovered/fixed.
1. Alliance tricks

Basically the idea of most points in this section revolves around two teams flipping back and forth between peace and war to abuse certain game mechanics.

1.1 Getting double-duty out of artillery and Workers

Two (or more) teams can get double (triple...) use of bombardment units and Workers by using the units on their respective turns, then letting their "enemy" capture and use them in turn. When facing an alliance of two civs with 20 Catapults among them, it's quite disconcerting to have to face 40 rounds of bombardment.

The simple solution is to require alliances and peace treaties to be respected through in-game diplomacy.

1.2 Sharing a Luxury or Strategic resource

Two teams can get the use of a single resource by repeated gifting and then cancelling of the trade. One Iron should only supply one civ at a time.

Repeated cancellation of trade is okay for supplying bursts of a resource for a civ upgrade, as long as it is not also being used for making a dual supply out of one resource.

1.3 Generating Leaders by sacrificing cheap units

A team can build a bunch of Warriors and let another team slaughter them with Elites, in hopes of generating a Great Leader. This is actually quite costly, but the results can be dramatic (fast Forbidden Palace or Palace) if the teams get lucky.

The solution to this one is the same as in 1.1.

1.4 Declaring war for happiness

Two teams can declare war on each other for purposes of generating a little Happiness, which can lead to increased production through WLTKD.

1.5 Exchanging map/minimap information before Astronomy.

In Conquests, map trading is pushed back to Astronomy. If two teams can exchange maps out-of-game, the Seafaring trait becomes a lot less attractive.

2. Metagame tricks

2.1 Reloading to alter unwanted random results

It is possible to alter the results of combat (even with preserve random seed turned on) by reloading the save and playing out the turn slightly differently (i.e. by attacking in a different order, or basically by playing around with things that trigger the RNG). This can result in finding highly one-sided battles, and the appearance of an inordinate number of Elites and Great Leaders.

The simple solution is to require each team to open the save only once. This means that only one sequence of moves/orders is allowed to be viewed per save.

2.2 Manipulating a savegame file

Crafty players use the PBEM savegames to obtain information, or worse.

Again, let's play Civ3. If we allow tools like MapStat, then the door is wide open for any other file-manipulation program, which is a can of worms.

2.3 Loading a save while zoomed out

A team's turn-player can configure his or her game to be zoomed out, then load a PBEM savegame, which can reveal certain facts about the previous team's location.

Solution: all teams must agree to zoom in before loading the savegame and/or zoom in before saving the game.

2.4 Renaming units/cities to confuse/mislead opponents

Cities can be renamed to names of techs ('Monotheism') or sums of Gold ('210 Gold') or anything else that can be traded in the diplomacy screen. This allows a team to screw over another in a very weird way.

Worker and Settler names can be interchanged to hide their identities in stacks (since their stats are the same). Units with identical stats can be renamed for the same effect (Enkidu Warriors and Spearmen, Ancient Cavalry and Gallic Swordsmen).

Units/cities, therefore, may not be renamed for the specific purpose of fooling opponents.

3. Game Mechanics tricks

3.1 Fortifying a ship without any movement points left to obtain extra vision radius

A ship that fortifies sees an extra 1 tile in all directions at the beginning of the next turn. This can be accomplished by waking up the passengers of a ship (if there are any), and giving the Fortify All order.

3.2 Hitting F1 to change production

It is possible to use F1 to go into city views and change production before a city has been reached in the pre-turn production queue. This can result in tech-enabled units and Wonders being completed the very turn the tech is researched, or production to be changed in response to an enemy's actions (like Walls if a stack moves toward a specific city and not another).

3.3 Using GoTo to get extra movement

The last civ in the turn order can issue a GoTo command to a unit, and have that unit move twice before the next turn begins. This is very strong in war-time, and benefits one team only.

3.4 Chaining naval transports to quickly move land units across water

It is possible to wake a land unit at sea, and transfer it from one transport to another. Given enough ships, a chain can be created to instantaneously move units across bodies of water (by ending in port).

3.5 Teleporting units by abandoning or gifting cities

A team can instantaneously transport units from any city back to their capital by simply disbanding it or gifting it to another team. This results in very weird strategy.

3.6 Accepting a Peace Treaty from a civ then immediately declaring war

A team at war with another can accept the latter's Peace Treaty, then declare war afterward in order to eliminate War Weariness from that civ. This results in a huge advantage if the peace-seeking team is not aware of the trick.
