Swedish, and like most Swedes (and Finns) here I feel it was somewhat of an A-.
The UU's and the UA fits just fine to the period after we chased away them pesky Danes, the imperialistic "era of great power" (literal translation from Swedish), as well as the more diplomatic and peaceful 19th-20th century's Nobel-pricey Sweden-sans-Finland-Sweden.
The era in between those is barely hinted at, but neither is it really known to the general Swedish population ("
Like, some king got assassinated, maybe? Was it Bellman? Oh, and Russia stole Finland, I think? [Sweden actually attacked Russia, because reasons]
What's this nonsense about Hats and Caps?").
However, like the other Swedes/Finns here I still have two issues, albeit aesthetic, with the representation of Sweden:
Firstly, the king looks like Erik XIV, and not Gustav II Adolf, his face is very recognizable, with statues of him in many Swedish cities (possibly even Finnish cities, but I don't really know). Also, he refers to himself in-game as "the Snow King", which was the first time I've ever heard of it. "The Lion of the North" is a more well-known moniker around these parts.
Secondly, the city list, which seems to be a blend of modern day Finnish cities, and ancient Swedish cities, neither of which are appropriate to the period of Swedish history represented in the game.
The pattern of cities, as far as I can discern, is first two Swedish cities based on age, and then one Finnish based on size (repeat), all Finnish cities have their Finnish-form names, even though they would have been Swedish-form during the empire, I'll go through the list and give the choice cities a small review.
1.Stockholm, of course, as an exception to the pattern, isn't the oldest city, but has been the capital for a long time, including the entire modern period and is thus possibly the only city on the right place in the city list.
2.Sigtuna, while important during the viking and medieval eras really lost it's importance after the Kalmar Union, it should be further down the list
3.Helsinki (Helsingfors) should really be further down the list, just a small fishing town until the Russian era
4.Birka, an important trade-city. To the vikings, and not since, should probably not even be on the list
5.Uppsala, Sweden's answer to the Vatican, is a good choice, I'd go as far as saying it should be higher on the list, either second or third
6.Turku (Åbo), I'm not sure of how important it was to the Swedish Empire, but it certainly was the most important city in Finland at that time, it should be higher on the list, replacing Helsinki at least
After this I don't care much, my biggest beef is that Gothenburg (Göteborg), largest port in Sweden (and Scandinavia) and Malmö (third largest city in modern-day Sweden) is so far down the list, whilst Karlskrona is not even appearing, an important naval-base until we stopped with the whole "war"-thingamajig.
My proposed city-list would be something in the likes of:
Stockholm
Uppsala
Turku (Åbo)
Gothenburg (Göteborg)
Malmö
Karlskrona
Vaasa (Vasa)
Tallinn (Reval, Estonia was Swedish during this period too! something most people seem to forget)
Lund
Luleå
Helsinki (Helsingfors)
...Yadda, yadda, yadda
