<Snipped quote by Hael>

Heavily industrialized and populated but small.

A republic... kind of. There are some fiddly bits.

You practically are an island for all intents and purposes since you only have one neighbor.

But primarily the first one.
[/quote]UK wa anything but small during the first half of the 20th century. Sure, their mainland was no France or Germany but they possessed great number of colonies and had indirect influence over a few other countries.
Similarly Ventium and Avalia could switch places.
Also what made you choose Yllendthyr as Austria-Hungary? The same fact that Zanshin islands is the Balkans now and it'll be the source of the World War?
Similarly you could had PRK and Tin switch places.
PRK was described by you as formed after the collapse of something like the Byzantine Empire.
Tin is the large, unforgiving and undeveloped landmass which is only tolerated because nobody knows what to do with it.

Of course there's no point of taking a joke map too seriously. So don't take this to heart.
It was a fun map albeit trying to fit our nations to the map of Europe would be quite problematic anyways.
If you ask Yllendthyr's style seems to be closer to UK/France. I have snobbish, arrogant but self-aware and scheming leadership, centuries old government which is the mix of both old and "modern", imperialism and of course a lot of colonies.
