9).- Palabras Finales

  • I’ve put a lot of effort into making this concept. I hope it will help the developers in creating a possible Aztec civilization for the game, if not in its entirety, at least as reference material. Many of the images are sourced from the bibliography, though the icons for unique technologies, unique units, and bonuses are my own creation, except for those already present in the game itself. Without more to say, my regards” - GoldenArmorX.

I wish this was real
