For your enjoyment, West End Games - IMPERIVM ROMANVM II (1985).

If you play and create a saved game file for a setup of any of the scenarios, please e-mail me at and I will add it to the scenario list within the module. IMPORTANT NOTE about the scenarios: Some of the features added in the newer versions of the module are not backwards compatable with older versions. (I am referring to IR II versions...not Vassal versions here) Most of the issues center around the text labels and numerical counters used on the Power Forms and Mobilization Forms. As an interim fix, instead of replotting the pre-existing scenarios, blank and editable text labels and generic numeric counters of two sizes are available to permit players to use anywhere on the forms or map as desired. Note that refreshing the counters will erase the Province labels (but mysteriously,not any of the other labels).

  • Automated Siege Attrition Counters. Automatically counts each month that a city is under siege. ***Must be Zeroized before placing on map. (Counters can display any of the faction colors.

Version 2.0

  • About Imperium Romanum Version 2.0

Version 2.0 represents a significant upgrade in terms of automation and bookkeeping aids. Version 2.0 will manage almost every aspect of your major power's accounting. The Mobilization Form is admittedly a busy product but once players get used to its functions, the tedious manual bookkeeping will be a thing of the past. This version transfers your major power's treasury level to the Mobilization form. Players will select units to purchase by manipulating numerical counters that will be subtracted from the total Treasury Level, keeping players aware of all times of their spending amounts. Additionally, the counter limits are now possible due to a new pieces tray that stacks and counts your remaining available units by color. Finally, map overlays that allow players to quickly view the cultivation and road status for any hex have been added. Listed below are the specific upgrades for this version. Enjoy.

  • Enhanced Mobilization Forms
    • Calculates mobilization purchases
    • Shares Treasury Level with Power Form
    • Calculates Fortification and Baggage units
    • Icons to identify units available for each Mobilization Area
  • Phase Counters
    • Phase Counters available for 2,3,4,5 and 6 player options (So players wont have to click through players that aren't there)
    • Tracks each phase of the game
    • Automatically moves Month and Phase counters on map
  • Year calculator displays actual year and BC/AD. Automatically tracks through Phase Counter
  • Phase Flowchart maps the turn sequence
  • Period Map overlays - Display the Cultivation/Road status in a map overlay that can be viewed at anytime
  • Corrected missing pieces
  • Corrected missing names
  • Corrected Mobilization Area names
  • Counter Manifest board
    • Correctly limits units to the physical game numbers (Fortification levels are not automatically limited. Players must still keep track of the fortification maximum level any way they see fit. Possible future enhancement)
    • The number of units remaining identified by automatic numeric counter
  • Cheesy plastic tray lid simulator for pieces tray. Mimics the original plastic tray box.
