We do not seem to have a Pak128.Sweden-Ex subforum yet, so forgive me for making a general observation about this rather splendid nascent pakset here instead for the time being, it not being clear where else that it might go: the Simutrans way of doing town names is a little odd and does not work very well with country specific paksets. Because I am using the English language, I get towns named from a list of real British towns, giving me a very Nordic Sheffield and Manchester in amongst fir trees and fjords.
In Pak128.Britain-Ex, I get around this by removing the list of names, and instead using, in the English translation texts, a whole series of very British name components, from which the town name generator will then splice together names from two parts to create an array of potentially many tens of thousands of realistic sounding fictional town names.
At present, the name generator is very simple (pair a random first half of the name with a random second half of the name, and do not repeat any names), but even this allows splendid variety. One day, it would be good to make it more elaborate, although this is a very low priority. It would be splendid if the same could be done with the Swedish pakset, giving realistically Swedish names (and perhaps, in the English translation text, Swedish names with the spellings as would be written in English, if different) so that the towns appear correctly named for the landscape. It would be much more evocative of Sweden to see towns with fictionalised names such as "Flenburg", "Kungenholm" or "Osthalla" (as might be created by inputting fragments of real Swedish town names into a simple two part name generator as used by Simutrans).
