Playing RTW for the first time

[Zim]

You have to install patch 1.3, then 1.5, in that order (Your copy may already be at version 1.3). You can get them here, in the support-Rome section. http://www.totalwar.com/

I think there is indeed a bug-fixer mod here, but I play mostly major mods, and I'm not sure where to find it.

Edit: Forgot to mention, if you have the expansion, Barbarian Invasion, get patch 1.6 instead of 1.5, it will update the expansion and the regular game.
