For anyone still playing FE:LH with [LH 2.0] XtraDeconstruct: Legacy of Magic (23 August 2016) and associated mods:
I’ve recently gotten back into FE:LH with all its DLC and since Primal keeps this mod up to date and offers ever so much extra content this is the go to mod for my playing preference – not taking anything away from anyone else (Heavenfall, you’re great).
I’ve recently had a short conversation with him because (perhaps like other “micro-modders”) I change the ElementalDefs file to suit a few of my likes.
What was frustrating me was that I could not change the “MinDistancesBetweenCities” for his larger sized maps and I couldn’t figure out why. The answer is quite “easy.”
In Xtra Deconstruct this file is located in X_Shared and is entitled XH_ElementalDefs
You cannot add new XML tags for the new Snaky/Pangea map types or Gigantic/Colossal/Titanic/Gargantuan/Ludicrous map sizes. However, those new map types and map sizes will use the "next" value as set by the current XML tags.
So if you want to modify the MinDistanceBetweenCities for Medium Snaky, which appears, in game, before Medium in the list of World Sizes, then you need to modify the value MinDistancesBetweenCities_MediumMap.
If you want to modify MinDistanceBetweenCities for Medium Pangea, which appears, in game, after Medium in the list of World Sizes, then you need to modify the value MinDistancesBetweenCities_LargeMap.
If you want to modify anything appearing after Huge in the list of World Sizes (Huge Pangea+), then you need to modify the value MinDistancesBetweenCities_TinyMap.
Basically, MinDistancesBetweenCities_Map_X_Colossal cannot be used, but if you modify MinDistancesBetweenCities_TinyMap to 13, it should work for Colossal.
I can confirm this works as described. I simply changed all of my MinDistancesBetweenCities to the same number.
To end with a compliment: I like FE:LH, or rather, I wish I could like it much more. The game could be more stable and it could have better polish (the direction of Sorcerer King) but with [LH 2.0] XtraDeconstruct: Legacy of Magic I have renewed interest.
If anyone has interest in my ElementalDefs I could always throw it on Nexus.
