[*]Currently my mod is more than 80 files big. Would it increase the mod's loading time a lot if I merged all the individual CS xml files into one?
The trade-off would be strongly diminished user-friendliness of deleting CSes, so I won't do it if the impact is minimal.[/list]
Nice leader image quality - looks like they belong in the base game and not a mod.
I've found in my mod that combining XML's doesn't really make a difference for load times. What does have an impact is .dds files. I've had some success in limiting load times by combing .dds files and adjusting their position on screen, although this process is fairly tedious and requires a lot of trial and error.
Having the game reload unit/landmark systems also adds a looonnngggg time to game loads.
Have you been tweaking the flavors of these new Minor Civ's? From quickly browsing the XML's it seems you can adjust things like if they focus on building Wonders or Nukes or even Expanding, (along with other flavors like Military Training, Defense, etc). What would be really interesting is if you tweaked these values to the
extreme. You could, for instance, max out Belgrade's offense rating and military training rating, then adjust the <Language_en_US> XML's from Militaristic, or whatever trait it was, to a custom worded trait that reflects these new flavors. Even if you don't alter the XML for the trait, you could enhance an already Militaristic Minor Civ with maxed Nuke/Offense/Military Training capabilities and call it "anarchistic," as an example. It would be interesting to run across Minor Civ's, all with their "own" unique trait that you've molded a certain way. To make things really interesting, you could play around with the UI and list these flavor ratings, (not by writing flavors, specifically), but by calling them specific government ideologies similar to how Social Policies reflect certain ideals.
If it's impossible to adjust the UI for the <Language_en_US> Trait titles, you could just add a line underneath the main Trait title, alter the color of the letters, and have this as a sort of sub-trait that further expounds on what level of "Militaristic" that specific Minor Civ really is.
Whatever you end up doing, good luck. It's a nice mod you've got going.
