This is a very interesting recent video:
The guy covers:
- How he painted the minis.
- Unit size (and variations due to different rules)
- Compatibility with Kallistra minis (he has a Kallistra command group for one stand)
- How easy it is to convert the minis to wearing all kepis (liked that!)
- How fun it is to play Ultimate General Civil War (which I am also doing right now)
