There is another comment that says this, but for clarity there is a franchise called "Total War" that has multiple editions which is exactly what you are looking for. They also have the ability to control the specific battles on the field like an RTS or you can play it with the battles operating like Civ. I personally really like the Total War Warhammer 3 edition (but I'm a Warhammer fan).

Domination victory is literally one of the victoru conditions of Civ 6. You're allowed to go full steamroll and go to war with everyone. Some of the civs are focused on going to war and expanding quickly through warfare like the Aztecs. Just don't be surprised when you keep attacking other civs and the other players use the other diplomatic strategies to their advantage.

I'm Civ it's also important to know how the other players perceive you and how to manipulate that perception to your advantage. Manufacture Casus Belli, poke and prod until others make the first attack and you "defend" yourself by taking their cities. You'll be less of a warmonger.

I mean… it CAN be the point of the game. Wouldn’t you expect some pushback if you decided domination was your path to victory?

Total war is fantastic and fits the bill.

Try Stellaris. It's similar gameplay, but it's realtime and the space battles you can get yourself into can be truly epic.

Warhammer 40,000: Gladius - Relics of War.

In the grim darkness of the far future there is only war.

Maybe Hearts of Iron or Stellaris?

Any total war game really, you also get the fun of actually commanding an army.

Probably the Total War series is up your alley.. sounds exactly like what you did in Civ 6.. you amass a giant army and go around putting everyone in their place.. and often enough someone shows up to put you in yours.. also for the combat you can just select auto and it will just do the battle for you, ORRRRR you can manually do the combat and control each of your units (cavalry, swordsman, officers.. etc) it’s really pretty neat if not a little overwhelming at points.

I don’t understand. You want a game where you can go to war with countries that won’t declare war on you?

CIV 5 is better than CIV 6. You can be a war monger but the effects are less than 6.

For pure carnage, CIV 4 Beyond The Sword.

Crusader Kings 3 is my favourite game like this. I wouldn't say the point is to go to war, but it's a pretty big part of the experience. Has a lot of DLC but you can definitely have a ton of fun with the base game if you don't want to commit to that.

You might like Age of Empires (2 or 4)

Isn't that the point of the Ghandi playthrough?

Diplomacy Is Not An Option, maybe?

Wait, that's not how you're supposed to play Civ? Is there any other way?!

The game "Humankind" plays very similar to civ 6, might be better to compare it to being inbetween civ 6 and 7. But it has a much more tactical combat system.

Hearts of Iron IV. It’s a grand strategy but War is the whole point.

There was an old computer game Warlords. It was turned based and you can even play it online nowadays.

Warlords

Real life

Age of empires 2

It works as in real life.

If you want a world where everyone welcome your power, that can only be achieved economically and with endocrinement as religion, media...

There's no politics when everythings' mere existence is heresy

Not 4x but close

Total War: Warhammer III

Civ 3 works well with a warmonger style
