It's not really new, just under the radar - but maybe Paradox Interactive's grand strategy games would be up your alley. Look at Crusader Kings 2, or Europa Universalis 4. I make this recommendation reluctantly as I despise their DLC practices, but those games are pretty great and fulfill an underserved niche. If you do decide to play them - I'd try out the base game before considering DLC, there's just way too much.
