Yes, snow and cold versus sand and heat; different tactical doctrine, etc. If the game engines are the same then making the databases for troops and equipment and environmental variables (i.e. sand, snow, doctrine) "open" rather than hardcoded in the main program would allow us to not only convert scenarios but create accurate scenarios for any theater using a single game. Sand, snow, hot, cold, Japanese, British, Soviet, French, whatever....all of that could be changed. The program pulls the variables that make the Soviets what they are from somewhere, variables including the way they move and fight to how they look and what they fight with. Maps, terrain effects and weather effects come from somewhere, too. Stick those things in files that we can tinker with in CM2 instead of in the main program or in a closed file.
