As you may remember, it allows you to have Ouposts with wizard towers! Undead Tigran heroes! An elven hero with death strike and Hellfire and items that turn you into an animal! All you can imagine. Make such a map, playable under v1.4 'standard' rules!
(Examples can be seen in my 'old' Drums of Death map)
Thanks, I really disliked making it (again) although it's such a good thing to have!
Just to avoid confusion. When used properly, it only affects the starting position of you map. You should never play the game under these 'modrules'. They are for editing maps only!
You can already remove build options with the city limits. What this mods lets you do, is allow buildings to be active in cities/outposts that would otherwise need prerequisites.
For example, if you want to manipulate a slow growth of a player in your map, but you want them to be able to build a lvl 3 Chaplain with low production. You can now preplace the Chapter House in an Outpost, or a village without need ing to have a Temple, Barracks, etc... You can see this in DoD. Try playing Lady Godiva and watch where Dalviana resides. In her tower, you can already build SpiderQueens in a map that has a high emphasis on the use of low level units. This might seem unbalancing at first until you look at the production rate needed for them.
Well, Magog stated that no mod can be used, but since this is technically just a support-tool, it might be ok. This mod should also not be activated when playing so...
