I have all of them, I think
The favourites, RUS and EAW, probably because of the topic.
Most played (and modded) though was NCP, the first one that introduced me to Ageod.
Not your question, but let me say which ones I want now. The three PWs in not particular order:
- Pacific War (WWII).
- Peloponnesian War (Ancient).
- Peninsular War (Napoleonic).
