Not quite sure what to make of this one. Its described as a tool for recreating battles and simulating potential outcomes. As such, the developer says it is not really intended to be a "war game" per se.
It looks interesting.

QuoteIs War Room a conventional Real-Time Strategy (RTS) game?
No. War Room is fundamentally an educational sandbox tool and a creative workspace. It does not feature scripted campaigns, base building, tech trees, or resource gathering. It is a software designed for those who want to "set the stage," explore historical events, and express their creativity.
Does the simulator support any type of unit and map?
You can import any PNG file to be a unit (soldiers, ships, tanks) and any image as a map.
Who is the ideal user for War Room?
Military enthusiasts, Kriegsspiel players, Historians wanting to visualize battles and YouTube content creators.
Intersesting. I purchased it, as it may be useful for doing some video AARs of games
