Ever since Civ 6 was released I kinda wanted to get into it but I couldnt. I won a bunch of games in Immortal with all victory conditions, but I am still trying to get into it.
In the meantime, I played my first Deity CiV game in almost 5 years. I was worried and felt rusty, I hadnt touched the game in 5 years! Nevertheless I wanted to try my most favourite VC, Domination, with my favourite civ: Germany. I won a Deity Domination victory before with a Tradition 3 cities strategy, I think you can find it in this thread.
The starting location was extremely good with two salts, and my 2nd city also had access to two salts. I was able to take a couple cities including the capital from Persia, and then teched to Scientific Theory-Dynamite. I became the tech leader in Industrial Era.
The Germany is just so powerful with Liberty Domination. I had three extra units from camps during the opening stage, which allowed me to take out Persia relatively easily. Japan DoWed me during the midgame but I was able to defend with some well positioned citadels and counter attack, taking one city. After Universities, Hanse and the Trade Routes kicked in, I had four cities with a lot of pop, good science, and extremely good production. After getting my artillery, I went through Japan, France and The Huns. The Panzer is an incredibly good late game unit and I had a lot of fun again.
So for anyone still playing CiV BnW vanilla like me and want to try your hand at Deity Domination, this strategy is the way to go. If you want an easier time, I'd suggest to go with Persia because there's so much synergy between the Immortals, Liberty and the Golden Age which allows you to just steamroll your first target easily.
