Oh, God, I forgot the biggest one for myself:
Make it so you can use the Space Button for pausing the game AND renaming units! Nobody wants to use Pause Break, it's such an inconvenient place for a button you have to use so incredibly often, I have to hold my keyboard so awkwardly!
That's actually interesting because when i played Hegemania(don't know spelling) i hated space being pause, if they implement that then there should be a way of changing it back!!
Developing interwar scenarios and a cold war one would take ages so i won't suggest it being as it has been repeated loads. (i want them but i think this thread was aiming at smaller things)
Suggestions -
-Convoys do need sorting out i think, even if its just for trade (AoD does have a good trading-convoy system that you might be able to make more efficient)
-CHINA,CHINA,CHINA. As Japan it is really hard to force them back from the initial frontlines. AI Japan manages it somehow but it always wins or loses, it needs to be altered somehow so its more even(this would be difficult being as japan will need to also invade india,indonesia and the pacific islands). also under this suggestion, communist china needs to be beefed up (in reverse to nat china being down powered) i've always wanted to play as commie china from the start of the civil war to the unification after ww2 but it will never happen as it is. (i don't blame the devs as not much CW work has been done yet)
-I noticed the guy on the first couple of pages talking about light ic and heavy ic, this would be almost impossible to reflect in game i think but i reckon that there should be some form of "market" for weapons for the weaker countries so they are better to play as. (honestly who doesn't play as the Uk,USA,France,Germany,USSR,Japan or Italy??... no one...... yeah i thought so...)
- (this is an interface suggestion..ish) Synthetic Oil factories like AoD, i miss them. It's the main thing that i do miss, it's one of the main things it has over DH for me.......
