Nope, for AoW1 we play on the base game aka TS136
PBEM works out of the box? I won't have to manually send email files?
Any rules? Battles always on auto?
Oh right, I forgot you haven't played PBEM before.
For sending and receiving files, you will have to either do it manually or install this, which I for one use: http://aow.heavengames.com/downloads/showfile.php?fileid=1122
The Wrapper can have some fiddly stuff needed to set it up, but I'm sure we can advise if you run into any issues. Also, it comes with an effective manual.
Battles between players are always automated because of course only one player is present, but vs indies you can choose.
