Breakthrough vs Original SCWW1

Recommended Posts

Am in the middle of two Breakthrough games, my first. Cannot find any noticeable differences from original SC WW1. Mind you I was away from the game for a year.

Can anyone provide a list of differences? The only thing I am finding, and it may be my playing is rusty, is the game is bloodier than before. Lots of unit losses...did the formula change and defending units get weakened?

The key differences will be the German Deployment Phase, and Germany can delay conflict with the British by respecting Belgian neutrality.

There are also the new supply rules, whereby units defending resources that have been cut off from their home territory will now find it much harder to hold out, and damaged HQs will provide reduced logistical support.

Below is a full list of all the changes since. If you skim read it you'll see that there have been a lot of improvements to it, and some more relating to diplomacy (especially Romania) are worth taking note of.

There isn't any specific change that I can think of that would make things bloodier though.

I hope this helps, and I hope you're having fun! :)


- Romania now swings 1-3% per turn towards the Entente from January 1916 if Belgrade is in Entente hands.

- Removed Antwerp from the Belgian capital list and made it a Secondary Supply Center.

- Capturing Mulhausen will now boost French National Morale by 500 points (Altaris).

- French Cavalry unit script text added (Xwormwood).

- Mainz moved to the Northeast and the Rhine and Eifel adjusted (Hyazinth von Strachwitz).

- Mannheim is now a National Morale objective rather than Mainz (Hyazinth von Strachwitz).

- Frankfurt am Main added as a National Morale objective (Hyazinth von Strachwitz).

- Alexandria is now a National Morale Objective, and its loss will penalize the UK by 2,500 points.

- The loss of Cairo will now penalize the UK by 2,500 points (it was 3,000).

- The loss of Port Said, Ismailia or Suez will now penalize the UK by 250 points apiece.

- The loss of Egypt will now penalize the UK by 50 National Morale points per turn, representing both the blow to Imperial Prestige and the effect of the rerouting of trade via South Africa.

- The Ottomans will receive a boost of 2,500 National Morale points if Egypt surrenders, and the Germans will receive 1,000 points.

- If through diplomacy Norway or Sweden swing to a position which is friendly to the Entente, then Germany will suffer a National Morale penalty of 750 points per country, representing the effect of the political isolation of Germany on morale.

- At some point between March and December 1915, Romania will increase her armed forces by adding a new half-strength Corps, as well as a half strength Heavy Artillery unit. Both will arrive with full research.

- If Romania joins the Entente then Russia gains 2,500 National Morale points.

- If Romania joins the Entente then Austria-Hungary will lose 50 National Morale points per turn to represent the loss of vital food imports, for as long as Romania is in the war. It is therefore now more beneficial for the Central Powers to keep Romania neutral, and for the Entente to entice them into entering the war.
