Town Centre

In The Southeastern Dragon, the Town Centre replaces the Library as the main access point for technological research. Town Centres now differ from Libraries in that they also follow the 4 x 9 grid plan used by Civic Centres from Kings &amp; Conquerors, and require Knowledge as a ramp cost (their base construction price remaining unchanged).

This new ramp cost can be quite costly, and in addition, Town Centres now produce a hefty bit of Knowledge when torn down. So it is of vital importance that you protect them from the enemy whereso possible, or to save town infrastructure wholesale when you take a city from the foe since Town Centres take a long time to erect in any settlement.

France have the benefit of cheaper Town Centres, so this allows them a faster means of escaping the Mediaeval Era and getting better units and a stronger economy.

Trunk research
Only one technology, Classical Age, is available and it is free and instantaneous. You will need to research at least 14 technologies from the Civic Centre before it can be accessed.

The most important branchof resarch in the game, Military research raises your Population Limit and the number of new units you can access. A successful game will require you to raise your population cap as far as possible, and to upgrade and access new units whereso possible.

Administration research [[file:2009-06-26_16.00.10.jpg|Administration|link=Library/Swords of the Prophets#Administration research]]
Because of the absence of trunk technologies in Swords of the Prophets, Administration research often functions as the "Ages" of this mod. So, a lot of military buildings beyond the main vanilla ones just can't be accessed, unless corresponding buildings were also constructed too.

Scientific research [[file:science.jpg|link=Town Centre#Scientific research|Science]]
While seemingly innocuous, Scientific research shouldn't be sniffed at. It will go a long way to unlocking new building and war machine types, while increasing the economic yields of your civilisation whist reducing the cost of research and upgrading.

The most common units requiring Science research usually tend to be siege machines, but even then they require auxiliary research in order to be unlocked.
