These are the original AI files from Age of Empires Rise of Rome. AI files tell the computer which units to train, which buildings to build, and which upgrades to research. They are still the same and also work with Age of Empires: Definitive Edition.
These files are easily accessible in a subfolder for all gamers who have the original Rise of Rome. They are still used by the AoE Definitive Edition but not accessible, and more deeply hidden in the code.
You can look at these copies of the files, learn from them, copy from them, adapt them and use them to create your own AI files in your Age of Empires scenarios.
These files were created by Ensemble Studios for Rise of Rome. I did not create these files, and I do not own them.
