"The Great Conflicts 872-1071" mod came in to its 0.9.2 internal build.
So far we use a number of Buildings UI CARDS from Attila, Vanilla M2TW and RTW ones.
In my eyes RTW/BI building UIs are the best made so far (exept few Attila exeptions).
Few years ago we made an experiment to modify RTW building icons.
Here is an example:
Fortified port:
Here is an other example:
Byzantine Armory:
Absinthia made a great job modifying that RTW port but the project remained unfinished.
We call any artist that could use RTW and Attila building icons to create a full line of such modifications, to join our cause to deliver a mod that could stay in history after I will be gone...
