My personal medieval2.preference file, to be placed in the main directory of your Medieval II Total War game. As in Sega/Medieval II Total War - it is needed as otherwise the new version of Warcraft Total War will crash after entering the campaign, as soon as the player is clicking on a building - this is due to the FMV videos of the Warcraft Total War mod. By deactivating the videos one could also solve the issue, but by using this file the videos should work fine with the mod in the main menu and intro screens. Also, it makes defensive battles work in hotseats - without it they would most likely be automatic which is annoying if the AI can beat you in autoresolve.
