This mod aims to add every flag to minecraft. It keeps the vanilla style without using high resolution textures.
Currently, it only features the 196 country flags without territories or historical flags.
In the current version 1.0.0 the flags do not have recipes yet, therefore only obtained in creative, so I am working right now on a way to get them in survival mode.
I will also eventually have an information page for each flag with a bit of a history lesson.
