As many have pointed out, 1936 is the start date of HOI3, so there's little point in simulating the period beyond 36 with the military (especially airpower) model at hand
Having said that, you can always mod your game to last as long as you wish, tinker with the RP-gain and you can make the tech fit any timeframe.
Ive never really gotten this explanation, given that the last startdate is 1861, the world wont reflect that of HoI3. It could easily run an additional decade of two without necessarily needing new mechanics. And the military isnt everything anyway.
Maybe a extra line of technology or something. Or even remove the end date entirely and have it run till it breaks or you want to start anew, though that would need alot more technologies just to keep things changing on all fronts. Maybe technologies that decreased things then followed by technologies that increased them again. That way you wouldnt run into too many problems of excess as things would cycle if new techs brought things back to 1830s level then back up again you could theoretically put in a couple centuries of techs without surpassing the levels the game was designed for, and thatd probably keep things uncertain as leading nations would fall behind.
But i do agree that thatd be something best left for a mod.
As to the expansion, one thing ive been wondering, will there be an offical frontpage listed thread for the announcement or will that hold off until the first DD or something?
Not an important thing, ive just noticed that theres people who havent noticed this yet.
