What would you do with this campaign??

[Xurr]

I'd do the following

Take out these in the following order

1) Arverni
2) Aedui
3) Sweboz

Consolidate your armies after that campaign. Move a couple stacks down to the north African border with the Ptolemaics (these are for later). Take the rest of your troops and take out Makedonia. Once you finish off Mak start moving the North African troops in on Alexandria. This way you have a nice 2 pronged attack on the Ptolemaics and essentially just 1 front to worry about.

Note you probably wont have to worry much about the Getai, I find they tend to spend most of their time going north.
