My personal wish-list taking
https://forum.paradoxplaza.com/foru...ry-1-5-2-future-roadmap-and-ironclad.1088407/ into consideration:
For the First DLC, please finish the homework - NF-tree updates for SU and France (perhaps in addition with Scandinavia) and fix all the broken or missing political stuff, e.g. the peace conference system and espionage.
Then in the second DLC Wunderwaffen would be nice - but please remain reasonable. Long Range Guns (
https://en.wikipedia.org/wiki/V-3_cannon), Rockets (
https://en.wikipedia.org/wiki/List_of_German_guided_weapons_of_World_War_II), gluide bombs (Henschel Hs 293) and heliocopters (
https://en.wikipedia.org/wiki/Sikorsky_R-4,
https://en.wikipedia.org/wiki/Flettner_Fl_282) were all more or the ready-to-use at least at the end of the war, there is no need for Return to Castle Wulfenstein stuff.
Along with the Wunderwaffen, the NF-trees in the Mediterranean could be updated (Italy) or introduced (Spain, Greece, Turkey).
My third wish for a DLC would be updates for the air-warfare mechanics like the possibility to make certain squadrons use certain airplanes (and types of airplanes), ways to represent air-to-ground missions of fighters (which was quite common) and some way to integrate air officers into the game a bit more than now. An airplane designer would be nice to have, but less important than the ship designer. Along with this, a NF-tree update for South America would be great.
At this point, the game would feel somehow "complete", at least for the 1930s - 1940s era.
