How many days, till we a 1 billion?
Please tell me!
Somewhere around 170 days.
About half a year, little less, yeah. My oldest nation is now over 4 billion, after playing for almost 2 years.
170 days would be on the long end of the spectrum for you. It's random how it will work out for you, but you should get there just under 5 months.
Out of my two nations one was shorter than 5 months and one was longer, so you never really know.
