How to make accurately scaled map when pasting cities in

Hi! I’m trying to make a RTS game similar to Rise of Nations, but of course I’ll add my own little spin on it. To add cities, I used a database and got 2000 of the most populated cities in the world and pasted the CSV in and converted the longitudes and latitudes to real life positions. I have tried a few projections on a map but I am not sure what I should exactly do to make it line up because it isn’t. The size of the map I had set to 360,2,180 (which is accurate to real life), and the cities are showing up just outside of the correct locations. I don’t know what projection to use, and if there is anything else that could help me with this.

This is an image showing that is wrong:
