'Anno 1800'.
A recent installment in the well-received Anno series. A masterpiece in the city-building and strategy genre.
It's been out for about...
405 years in the future.
Ugh, that feels strange.
Anyway, the game itself is worth playing. I've probably spent over a hundred hours on it since I like the 19th century setting and the graphics are pretty decent.
Anyway.
In this game, where you grow your own city set in the 19th century, you can interact with other cities and factions through 'navigation'.
And the ships used then are exactly from around the 19th to 20th centuries, making it perfect for reference.
Especially since our technological capabilities related to steam engines awkwardly straddle the period from the 18th to early 19th centuries.
Of course, this isn't an educational comic, so there are no particularly detailed blueprints here. It just gives a modest understanding of what kinds of ships existed in this era.
