Explained: Axis & Allies Global 1940 House Rules Expansion

The scale is the thing that most bedevils me.

I was recently watching some commentary on house rules from [b]Lion in the Trenches[/b], who was reacting to suggestions that he place an Austrian cruiser in the Sea Zone off Tsingtao in his Global 1914 customization. He made the point that a single Austrian cruiser doesn’t scale with the squadron or fleet implied by the corresponding game piece.

By my estimate, Global 1940 models ground units at the level of army corps, naval units at the level of fleets or task forces, and air forces at the level of wings. There are a handful of exceptions for colonial detachments, such as the two starting British Infantry in Kwangtung (Hong Kong), which stand in for about 14,500 defenders historically. India’s potential as a source of colonial manpower is significantly curtailed by the British Empire’s income problems, and Australia often explodes in production by the end game (win or lose) even when their national manpower pool and industrial capacity would never have allowed it.

In my opinion, scale should be balanced rigorously against the opportunity for fun gameplay. In my Global War games, I always add a French Infantry in Indochina, for example. There is also a clear movement in favor of bulking up the Dutch presence in the East Indies when games of Global War are played, and many players prefer to give the Italian fleet-in-being a fighting chance with set-up variants to blunt the Taranto Raid.

I personally have more than one way to “win” the game for each side.

Axis -

Economic Victory - The Axis powers make 150 IPC’s combined
Total Victory - The Axis powers control all Allied Capitals
Victory Objectives - The Axis powers have 5 Victory Objectives
VC Victory - The Axis powers control 12 Victory Cities or the OOB rules

Allies -

Economic Victory - The Allied powers make 200 IPC’s combined
Total Victory - OOB Rules
Victory Objectives - The Allied powers have 5 Victory Objectives
VC Victory - The Allied powers control 16 Victory Cities

World Domination is also a possibility, one we play when we have time.

@KimRYoung:

How about making Sicily important!!

One of the major campaigns of the war is simply not a part of this game whatsoever. It should either be worth some IPCs or at least of value as an NO to the allies. Pretty ridiculeous that there is no reason to invade an island that was of historic importance.

same could be said for the Solomons too!

Axis and Allies D12 system rules:
The purpose of this is to integrate the new pieces from HBG as well as new sculpts from AA41 and AA42.2.  The goal is to fit all the pieces creating unique values into Axis and Allies games.
I had considered using different unit values by nation, but this proved too difficult. The utility of using D12 allows many new units each having unique characteristics.

Note most OOB units are double attack and defensive values: (Attack-Defense-Movement-Cost)

Infantry: 2-4-1-3
Artillery: 4-4-1-4
Mechanized Infantry:
Armor: 6-6-2-6
(Note: these are considered mid-war tank design and can’t be built till turn 3)
Fighter: 6-8-4-10
Tactical Bomber: 6-6-4-11
Strategic Bomber: 8-2-6-12
Battleship: 8-8-2-20
Cruiser: 6-6-2-12
Destroyer: 4-4-2-8
Submarine: 4-2-2-6
Carrier: 0-2-2-16
Transport: 0-0-2-7

New WOTC sculpts:
Note: These cannot be built as early as turn 3

LAND:
Heavy Artillery: These are a 6-4-1-5 unit and have a special feature. If they roll a one result in combat, the defender must select an air or non-infantry land unit as a combat loss.
Late War Tanks: These are 8-8-2-8 units and can blitz like other tanks. In all other respects these perform as tanks. These tanks can be built as early as turn 6.

SEA:
Battle-cruisers:  These are 7-6-2-16 units and like Battleships they take two hits. They also bombard at 3.
Super Carriers:  These are 2-4-2-18 units that carry 3 planes. They also take two hits, but the first hit does not affect their ability to launch or land fighters.
Destroyer Escorts: These are specialized units to protect convoys. They have a movement of 3 spaces or four if leaving a naval base. These are 4-2-3-10 units and have the same abilities as a destroyer, except as long as you have at least one Destroyer escort, all transports in the same sea zone as the destroyer escort defend at 1.
Heavy Transport: These perform just like Transports, except they carry three Infantry or two armor type units. These are 0-0-2-12 units.
Advanced Submarine Design:  These are 4-2-2-8 units and have special abilities. They can avoid combat with destroyers or destroyer escorts at a 1:1 basis. If you got for example 2 of these subs and you enter a sea zone with 1 destroyer escort or destroyer, they can avoid combat and  pass thru into the next sea zone. If for example you have 2 of these units and get attacked by at least 3 destroyers, combat is performed in the normal fashion. If at any time the destroyer count is equal to the submarine count, the advanced submarines can submerge immediately.

AIR:
Medium Bomber: These are 6-2-6-9 units and have a number of new features. They can  perform SBR like any other Bomber, but are the only units that can  pick up Paratroopers
Advanced Fighter design:  These are 8-8-4-14 units. The key feature is their ability to be used somewhat differently in SBR. In these actions they get a +1 in combat as escorts or as interceptors.

Hi, just joined the website, but I have been playing A+A for a long time.  My friends and I played with our own rules, but they  were all even balanced for the most part.  And ohhh boy did we play!  Did all of you get the dreams?  I swear some nights I would have these dreams like “I had three tanks, 5 guys, and 2 fighters….”, replaying these battle sequences in my dream!

We used 8 sided dice, 18 different units not counting artillery, AA gun or IC, 3 different Tech charts with 8 techs each. We had Auto buy which were free units at the star of your turn and Capital Surplus which was a roll at the end of your turn, if you get a good roll then you get a free piece.  We used the Cards of War, which is a deck of cards that I made which help on offense, defense and misc situations.  And of course we played on a home made map.

Before Artillery was introduced in the AA Europe Expansion I think, my friends and I had a custom piece called an Artillery that  was different than the official rules when they came out.  It all started with Germany…how times has an Axis player faced endless UK and American transports just carting dudes in.  And how many times has there been a wall of Russian troops in Karilea?  So I came up with an Artillery…which was an AA gun with a country marker under it.  And it was ruled like a typical AA gun…only one per territory, one on a transport…etc.  but the special thing about the Artillery was that it rolled one die for every defending unit, and hits on a roll of a one.  That’s right…it cost 10 bucks and moved one space and had a range of 2 spaces.  If that isn’t strong enough it could also be used to attack naval units!  As long as a fighter or bomber attack the boats also, an Artillery or two (if in range) could be used as well.  So if UK had 5 transports and a battleship, Germany could attack that fleet with 1 fighter and 2 artillerys.  The artillerys would roll 12 dice total!  Oh yeah, they only fire once per battle.

But in time the aritllerys got used and abused, we even made a new tech called Long Range Artillery to make it really crazy.  Another tech we had was Gunboat Technology, which let transports holding an AA gun or an Artillery and fire then at land or air pieces.  Then another tech we had was Defensive Artillery which meant if you attacked one of my properties and I had an artillery in it, then before you rolled your attack my artillery would first attack you and roll one die for each attacking unit you had.  Any ones that I roll will eliminate one attacking unit.  That was a pretty cool, but not very reliable tech.

I played it for years and loved it.  I made many many maps, ordered countless extra units.  One of the custom units we had was a Chinook.  It carried one Infantry 5 spaces, it attacked at a 2 and defended at a 5, but that is using an 8 sided die.  I made it by cutting the props off of the choppers (special ordered with other pieces)… then I would cut a carrier in half and trim the edges down, then I would glue the chopper blades to the top sides of the destoyer piece and make a nice Chinook with it.

So many good memories with it, I have never played the revised, updated or any other expansion, but I am putting the 50th edition one on the Xmas list for sure!  Thanks for reading!

But I haven’t played it in years, and my stuff is in a storage place in New Jersey, so I don’t have access to all of my custom rules and new pieces.

If you love A&A Revised but feel it falls a bit short of it’s potential, try http://boards.avalonhill.com/showthread.php?t=15339  I would be happy to discuss the rules or even play a game with interested players…
