a year or so ago. and BFTB was done first because people wanted turkey a lot more than scandinavia.
To summarize basically. there were lots of factors why it didnt really get added here
- Balancing barbarossa and land warfare and supply is a huge task. trying to make the winter war super cool at the same time would require superhuman powers so we didnt wanna do it at the same time
- generally with the way the winter war was it needs quite a lot of love to play well I think
- there are tons of cool stuff thats only doable when you combine it with rest of scandinavia and it was awkward to split it
- We felt Baltic states were harder to do separately with the part in soviet history so thats why we did that over scandinavia (also doing all of scandinavia isntead would be too much work)
Several points to take away from this:
1) because a bunch of turkish players wanted Turanic memes in the game more than Scandinavia, Finland couldn't be included in the DLC with it's primary antagonist The Soviet Union (why was Finland ever grouped together with the Scandics in the first place!?).
2) because a conflict, which intrinsically contains aspects important to the Soviet Union (defensive warfare, winter warfare, guerilla / ranger style warfare) is hard to do, it is better to skip it in favor of Scandi countries, for whom only one (maybe...) that aspect is even remotely important in this time period historically
3) there are cool things to be done with Finland that need the other Scandi countries, which makes it more important to delay (for the fifth year now...), rather than to include her into the expansion with the country she had actual cool stuff to do with historically
Finland is now hobbled by being included together with Sweden for some arbitrary reason (cool content = Kalmar Union of 1938?). The game is five years old, and by this decision it will likely be at least one more year before we see what was so important with the Finnish ties to 30's and 40's Scandies that caused her to be ignored for all this time.
