Just so that this is clear, here's what I posted over at .com and then repeated at the Org:
1.3 Patch for Rome: Total War
There has been a little confusion over the 1.3 patch. This is a patch for the original version of Rome: Total War ONLY. You do not have to download this patch if you have already bought and installed the Barbarian Invasion expansion pack. The expansion pack automatically brought the original RTW up to version 1.3 as part of the install process.
Version 1.3 addresses bugs and issues that came to light after RTW version 1.2 was released. It does not - indeed cannot - take into account any new issues that people have found while playing BI. It's to keep RTW and BI in step, and allow multiplayer compatibility.
Now, I would like to write this next bit in letters of fire 3 metres high: we are currently looking into a further patch for RTW/BI. This does *not* mean that there definitely will be another patch; that's what we're trying to sort out. We want to make sure that any unexpected and difficult-to-identify issues are spotted before a patch is prepared. *When we know for sure about a patch, you'll know for sure.* How reasonable is that?
