I would like supplies for any given point to be drawn from several ports. Rather then supplies coming from port of X, I'd rather it was 50% of supplies from X, 20% from Y, 30% from z,l,k.
This fixes a lot of irritating bugs (!).
Something has to limit excessive naval sizes, in other threads this has been discussed as a dry-dock limitation for capital ship production. Capital ships should also cost $$$.
Spying currently works that the more spies you have the more accurate your information becomes. I'd like to see it changed to different classes of spies which can provide reasonably accurate information but only on a limited area.
For the theme I would prefer a modern scenario with a nukes on/off button at game start menus. There's been so many near-misses with wars in the last 10-15 years that a lot of events can be scripted for Taiwan/PRC, another falklands and Pakistan/India etc - it would expand the appeal of the game beyond the current ww2 fanatics
. The cold war is rather boring as it's two factions and the problem with WW I is that this is a divisional level game - divisions are meaningless in trench warfare.
I feel nervous about the level of detail being asked for in some of the other posts in this thread, if we wanted to play vicky2, we'd play vicky2. Simple fact is, some of this detail is actually too much. Nobody wants to play a nation that is going wrong with no understanding of why unless they've played 50+ hours (!). Much of the current game interfaces etc are actually finished from a development standpoint - it's exporting it to a different time-era that's needed.
