These are generic suggestions I post for discussion. In the end they are nothing but personnal opinions but I do believe they can be helpful in making choices when building a new civ. Leader Leaders should not be only military leaders. They should be political leaders to an extent. The classical/cliché/best/expected/whatever term you prefer representation of the leader should run in the Middle (for ancient civs) or Industrial ages (For more modern ones), NOT in the Modern era. In other words, a leader should be historical, not modern, unless the mod/scen calls for something else. A leader should be iconic, or at least self-explanatory for those having a minimal historical knowledge of the concerned civ. Esthetically-wise, battered versions should be tattered too: look at Battered Abu Bakr! Ideally, leaders are important unifiers that lead the civ during their Golden Age (the definition of the civ's Golden age may vary depending on the mod maker). City City lists should include as many names as possible as to avoid "new" duplicates. 40-50 is a minimum Choice of capital may be tricky when it has changed several times or does not conform to historic accuracy (foundation dates). You decide in the end, but in doubts, don't hesitate to offer multiple lists. City lists should avoid duplicating those from other civs. This might prove difficult when adding civs in crowded areas such as the mediterranea. You can always replace a civ form the same are for simplicity. Unique Unit A UU is iconic of the civ, at least for the concerned period. A good UU was present during the civ's Golden Age and played an important role (the definition of the civ's Golden age may vary depending on the mod maker) A good UU is worth building, either because it does things better, with less costs, easilier or does more things. The player should yearn to use it. Try to be original. Warriors, Archers, Knights and Swordsmen have been so frequently replaced it's almost boring. Look out for interesting alternative. Other considerations While the Military leaders list is a goood way to reuse unselected Civ leaders, it should be reserved for ACTUAL military leaders, who shouldn't be that hard to find! Now step back and give me your best shoots!
