Egypt Ultimate v1.5 is an updated version of Egypt Ultimate v1.4. A City Plan file is also included, to reduce villager traffic if there are more buildings. There are small modifications to the Personality file, but the AI file has some major changes to make the computer play much more smoother.
This AI builds walls, but they aren't always straight. They do provide an excellent defense against computer enemies, though.
When you use the AI in your scenario, remember that it is very defensive - but when it attacks, it achieves some successes - much more than a standard computer who attacks with 5 units at a time. Also, make sure you don't make the build-up area too small, or filled with forests, or lakes, that make computer players develop slowly. A way of controlling where the walls and towers are built is elevation. Place some elevation to the area (edge of the town!) where you want it to build its walls. Other things may influence this, too - gold mines, enemy attacks, ruins, etc.
