Game, where instead of collecting supplies, you receive income from your respective country but you can increase this income, by say, capturing a oil field like in Zero Hour, or capturing a town or killing large amount of enemy units. This will be reflected in game strategy, the Iraqis will have a easier time killing Iranian units but the Iranians will be able to hold on to these areas better. Also a note on superweapons, each side gets a Scud Missile, Iraq's is immobile but more powerful while Iran's is mobile but less powerful,has less range and is more inaccurate, and they can also call a large amounts of units to appear.
Now because the mod is so early in the developmental stage, I'd like to extend everyone the opportunity to recommend units and upgrades. I also have to call upon anyone with any modding skills but especially coding/scripting for ZH and the texturing of models. Please just drop a comment or PM me if your interested in Joining this mod's development.
Good idea making such a mod. You mentioned that Iranians are less powerful, remember that Iran had the upper hand in air and sea, since the Iranian army was totally provided with latest American warfare and technology. Also on land they were more capable than Iraqis. Finally do not forget the Iranians' spirit because they were defending their homeland.
They had an advantage on sea but Iraq had the upper hand on land.
