Hi Vaevictis,
What helped me allot when I started was the How to Win pdf guide located in the Punic Wars Folder. Some good advice on using the different units.
Also there is a good sticky here in the AWWC forum that helps with the different settings. I think even with patches, it is still relevant.

And here is one on some tactics - Very good! Especially on stacking, a critical component to understanding the game.

And definitely update to the latest patches. They not only address some bugs, but add allot of features too!
Also if you are looking for a game, drop me a line. I don't mind at all answering any questions you may have while we play!
