Difference between ver hard and hard?

[Apázlinemjó]

Pontos and Hayasdan campaigns are nigh-impossible on VH/VH and quite hard on VH/M, so if you look for hardcore challenge and fighting for your survival in every turn, then that's your campaign. Although if you manage to survive the early turns you can build a big empire with ease.

I don't think it's possible to change the difficulty level in an ongoing campaign.
