Wondering how we could make this a bit more entertaining than latium
We could use guadalquivir placement and maybe make this some kind of delta, i.e. one river from center to top and two rivers from center to bottom left and bottom right.
Or we coul add a valley south and a plateau north, similar to the volcano.
Or I could do that in a new map :P

The name "Winterland" is dull and should be replaced with a historical, geographic location.

From https://en.wikipedia.org/wiki/Volga_River

The ancient scholar Ptolemy of Alexandria mentions the lower Volga in his Geography (Book 5, Chapter 8, 2nd Map of Asia). He calls it the Rha, which was the Scythian name for the river. Ptolemy believed the Don and the Volga shared the same upper branch, which flowed from the Hyperborean Mountains.

So Rha were perfect if this guy had lived 200 years sooner.

For the name maybe "Snow Flakes" ?

Snowflakes is just as meaningless as winterland, it only describes the season.
But a 0AD map should be much more than that, carry geographic and historic information that make the player research history on the internet, books and documentaries and the latter should bring the player back to 0AD.

I think there was a river near teutoburg forest https://en.m.wikipedia.org/wiki/Battle_of_the_Teutoburg_Forest
Germany

Teutoburg forest sounds like a trigger script map with forests that we should have. For this map however we should pick something with river IMO.

Searching for earlier records of Volga, I found this:

Initial records of the Volga were found in the works of the ancient Greek historian, Herodotus, in 500 BC. In ancient history, the Volga was known as the Atil, Itil or Idil, a Turkish name meaning 'long river' or 'river of rivers'.

Then call it fight over Atil or Itil

I didn't requested any remove afair

Interesting note seems look like every other map too
