Blado, I played all previous versions to 1.1 on BI.exe.

And the main difference was the new naval ability of the AI.

Punic wars would start earlier, and more efficiently.
Rhodes, Crete and Sicily were frequently battlefields.

And because of the new method of attacking, I saw things such as the Romans losing Syracuse to the KH in rebellion, and then counter-attacking the KH holdings on the Crimea.

However, it did mean that whenever I wanted to play multiplayer, I had to uninstall everything - and I am a fan of multiplayer.

In addition, I no longer use it because apart from the naval attacks, no other great advantages are obvious - and 1.1 is on par with 1.0 BI.exe now anyway.
