Looking at my servers, Ambrosia gets you 2500 to donate to the Sawmill or 10,000 to donate to the luxury resource.
How much does 1 million Ambrosia cost? That's 2.5B to the Sawmill. Right now with the +80% offer, 9k costs £200. Let's round that to 10k for ease: I'd need to spend £10,000 to get 1 million Ambrosia. I find it difficult to believe that somebody would spend that in 3 months.
I heard that you can start playing on different servers of some less developed country, for example Turkey and pay with their local currency. So that way you can get ambrosia a lot cheaper. you then have to graveyard and then back on your main server. they would have to spend a lot of money still, but a lot less than 10.000
nosorog You are underdeveloped. Be careful when mentioning the Republic of Türkiye.
