I have been a fan of this game for quite some time, and I am currently contemplating doing an AAR of my own. However, I'm not decided on what you would like, so I will present some options below:
Whatever it is, it is going to be quite hard since someone already did Austria-Hungary Veteran, congrats to them.
1. Italy only (Triple Alliance) - This seems to be a losing proposition, but I'll try my best. What is interesting is that seems to be so many options just for it and it alone.
2. Allies with Gallipoli (Triple Alliance) - I've beaten the Allies Triple Alliance campaign on Veteran before, but I have not tried the Gallipoli invasion. I would be surprised if it was not at least a bit interesting.
3. Ottomans only (Normal) - Let me see if I could turn this stagnant and overly-pressured region upside down
No matter which option wins, since these seem so difficult, I would like to hear your opinions as we go along with the campaign. Cheers!
