So the Huns in AOE II Conquers has the special benefit that they do not need any housing and as a penalty for that, start with 100 less wood. So I a few minutes after starting a game, I found out that I needed to create more houses!
After some searching I found out that the full tech tree disables all unique stuff, inclusive the benefits, for the selected civilization.
So I started a new game with full tech tree disabled. And I still needed to build houses.
The part I did not tell thus far is that this is a multiplayer game with a custom created map.
Is it because of multiplayer mode that these benifits are not available?
