[2021] It saddens me that there will never be an anno game set in the 1900's

Arguably, there is some 20th century in Anno 1800 as well- battlecruisers, skyscrapers or using airships for arctic exploration.

We have also previously said that we would not let the “rule of 9” get in the way of a game we would otherwise be convinced of, but I don’t think the 20th century is high on the to-do list.

That the digit sum of any Anno year adds up to 9:

1+8+0+0=9

2+2+0+5=9

Etc.

Further proof that we can never be too old to learn new things!
