War for the overworld[0] is not only great, it’s fantastic. I’ve played it since launch and it just kept getting better and better! The devs where and are also great with the community <3
I like all of them, but if you want a more pure DK-like, War for the Overlord is what I'd recommend. Dungeons is decent, but the split between the above ground and underground isn't great.
The dungeons series is pretty much the same, focused on events and story. Overworld focuses more on building, micro/macro managing, exploring and combat.
