Hmm, well this mod is just for the GFX. If you go past it, that means the checksum will be different and thus it can bring trouble with multiplayer gaming.
You could make another modding thread that would be the Finnish History Project or smt. I think you could use the already finished
E3 map, it really improved Finland and actually added that 'slice' you mentioned. And I can help with the best of my abilities.
Indeed, there should be a random chance with the Soviet demands that could be more or less. Then if the claims result to the Winter War, it should generally be challenging for the Soviets, because they steamroll in vanilla. However the Soviets should get a significant boost around -40 and maybe an event replacing the old commander with Timoshenko. There also should be chances of Swedish/Allied invertion and aid. Thus also randomized chances with the peace negotiations. Not to mention events of evacuating the people from Karelia...
Then 1940-41 the events of German military access and military aid. Historically the Germans took care of the Northern Finnish Front, with some 200k men? When Barbarossa fires, the Finns could join straight away. Historically the Soviet bombing on June 28th or somewhere resulted in the war. So maybe the Soviets would be forced to bomb Finland and then it would join the war on June 28th. During the first weeks, Finns focused on defeating the Soviet garrison on Hanko, close to Helsinki. The E3 doesn't have a Hanko prov, so the battle for Hanko could be represented by locking some 3 Finnish divs or smt.
Then the Finns can choose to advance or not to advance beyond the territories they lost in the Winter War. Advancing would increase belligerence and give a bit of dissent. Cutting the Murmansk rail or capturing Leningrad would result in even more belligerence and maybe even some authoritarian slider moves.
Assuming that the Finnish advance begins to stall in 1942, there should be events for building forts on the border. Also the Finnish Army greatly increased size during 1942-43 to 500k men! Totally not represented in HoI.
In 1943-44, assuming that the Eastern Front goes historically, the Red Army pressure should grow enough to break the Finnish positions. Once the Soviets start entering Finland, that once again triggers the events of random peace negotiations. There could be some really interesting stuff, like Ryti promising to fight along the Germans for military aid and then retiring from Presidency.
Once peace has been made with the Soviets, the Germans are FURIOUS! So the Finns need to capture Lappland from the German troops. There could be an event giving the Lappland provs to the Germans (occupied status) and even spawning some German troops there.
So yea, a lot of interesting stuff could be implemented and I'm sure I missed a lot of other stuff. So if you got the energy and time to take the mod further, good luck and you can count on my aid. I lack enough time to take care of it myself...
