Which Mod?

I have tried to get this 1.2 everyone goes on about but after downloading it, it just disappeared

Hey,

You probably saved the launcher in your temp. folder. You should make sure your computer saves it to the desktop, at least you can't lose the patch that way. After that just double click it, and let the launcher do its thing. Also, make sure you install the 1.2 patch over your 1.0 version - but I dare say that's not an issue with your current install.

On mods...

Well, there are no total conversion mods yet, as it's too early for those to have finished by now. A popular mod at the moment is Lusted's Land To Conquer, you should contact him or search the forum (I can't seem to find a link at the moment, though I'm sure someone else can).

Id quite like one with more cities and where the AI isn’t so random and actually prepares for wars etc.

That said, there's a limit to what modders can do. And sadly, changing the AI is one of those limits...
