All really good, but why is "The Left Opposition" on the right side of "The Centre"? Let's try to avoid a Spain Tree issue with the Right being on the left side and the Left being on the right one.
As for the ideas about country packs, I am pleased with this. I personally want to see Scandavia covered first, just to finally get Finland represented. My biggest let down at PDXCON was learning Finland will not be in the Eastern Front themed pack. I understand this is the only logical way to slot in the Baltics, but I really wish we could see Finland too, with a tree really well integrated with the Soviet one. I also hope with Scandavia that Denmark gets at least a small tree, maybe focused on resistance post annexation as its population was quite good at secretly working against the Germans. I hope Norway can have a branch where Quisling gets his wild fantasies achieved as opposed to merely being a marionette of Hitler. Sweden? I feel they should have a tree to support the Fins, as many volunteers went to fight in the Winter War. Maybe also a very big diplomatic/economic tree focused on its iron ore.
Also on the matter of country packs, I recall Belgium was considered for Man the Guns but then dropped. This means you think it is important enough for some sort of tree. However I fear with the regional focus moving forward, Belgium will be neglected as all of its neighbors except tiny Luxembourg (confirmed to have no tree plans) have trees at this point. Please do not forget about Belgium in the long run. If the Baltics are worthy, so is Belgium.
