In Civ4 BTS all Nations have UUs and UBs. Thus the technical possibilities in DLL and XML also exist in Civ4Col since it inerited them from Civ4 BTS. Still this concept however was never really applied to Civ4Col. (It is basically only used for giving Nations different Missionaries and Priests that have the same balancing though.) We once discussed it in RaR but somehow never realized it ... (Mainly due to lack of ideas and time.) Why was it not realized then: We need to have good ideas for that, that match historical facts. We need to balance it well, because otherwise gameplay will suffer. It will be effort to create good graphics. (XML setup is relatively easy though.) General Pros: Nations would feel a little bit more unique. It could enhance gameplay to capture enemy Cities with such nation specific Buildings It could enhance gameplay to capture such nation specific Units of enemies ---- However, we should not overexagerate with it either. Thus I suggest to have for each Colonial Nation: 1 nation specific Unique Unit for a Ship (Combat Ship or Transport Ship) or a Land Transport Unit (e.g. Wagon Trains) 1 nation specific for Unique Unit for an Expert (Militarty Profession or Worker Profession) 1 nation specific Unique Building Small Remark: We could also do this by e.g. transforming some Ships we have to become only Nation Specific. (e.g. Caravela Redonda) ---- By the way: We are really talking about the 8 Colonial Nations only. (We should not be trying to do this for Natives.) We should also try to match the UUs and UBs to the focus and Nation specific bonusses the Colonial Nations already have in WTP. ---- Step 1: Clarification if we want to have it at all. (See poll) Step 2: Collecting good ideas and creating a gameplay concept (balancing). Step 3: Creating or collecting graphics Step 4: Implementation (configuration in XML) I am looking forward to feedback and suggestions. ---- First Draft of concept for Unique Expert Units: see here.
