Recently I've been playing Northgard, a game whose top tags on Steam are "strategy", "city builder", "resource management", and "4X".
It reminds me of Civilization in some ways - most of the gameplay involves expanding your borders, and making sure all your territories are contributing resources and happiness to your bottom line.
There are actual enemies, and you can build a few military units, but you can achieve fame or economic victories without ever attacking your opponents.
The biggest threat to your economy is usually winter. If you're not prepared, all work stops while your people wander around sick and unhappy.
Playing the campaign, I'm realizing that while I still love real-time games, I've lost interest in micro-managing hundreds of worker and military units a few units at a time.
I prefer the challenge of getting 5-80 people to survive in a hostile world by slowly shifting worker resources between important tasks. Military conflicts are fine, but I don't need them in the forefront of my strategy games.
