Alright. We here at the IS team would like to present you, the players, with an opportunity to customize the game a little more to your liking. So we will now, and in the future, post optional files here in this thread for you to download.
You cannot install more than one startpos.esf or scripting.lua file at a time (but you can have one of each type), so you must choose which you want. We tried to cover all the possibilities for you, however.
These files (with the exception of the Blue UI) go in your /campaigns/Imperial_Splendour folder, whose location is detailed in the main download thread.
As always, while we try to support everything that we put out for release, some of these files have known issues (such as turn length) that we cannot do anything about.
Additionally, all of these files are Multiplayer compatible.
