If the game is going to be improved, here are some potential ideas :
Put a port in Ireland (Dublin) and Belfast (GB) as it is not a desert, and naval moves should be allowed in and out.
Only one hex to attack Le Caire is too small, we have to bring massive support for only one unit. At the best two land units could attack, one to the left, and one from Sinai...And no naval support is allowed due to the blocking harbor.
Corsica and Sardaigne are useless deserts, they did have ports (small one, not for ship facilities, but enough to move troops), some retreated troops from axis moved there, and these bases could be useful to base air units and survey the path to Gibraltar.
Anyway, considering the lack of action in mediterranee, it could be considered useless.
The US industry is quite too small compared to the URSS one's. Furthermore, the game should enable land lease (gives of MPP from a country to another) for the allies AND the axis.
Considering the research strategy it could be more useful for the axis to set the Italy to NEUTRAL, declare war against it and plunder its MPP, thus gaining the advantage of already researched german technology with italian industry MPP (didn't tried but I'll do).
When a new level is gained in technology, it could be useful to have a button which allow automatic upgrade of existant units, providing you have the necessary funds (perharps by stages, or by random units, not all in one time, cause for Air and tanks it would be impossible to spend so much in war time in one round).
One thing would be great, I read that the game would last to 1948....thus, it would be great to allow a URSS "AXIS" side to allow "what if" scenario like Patton vs Stalin, a sort of started cold war.
Anyway, by 1948 the nukes would have been used since a long time, and perharps the germans had it too...
For paratroopers, I agree that they would be very useful.
BTW transported naval units should make amphibious assault (Malta, Gibraltar) as we can't actually.
Perharps the game should enable to buy some fortifications (Atlantic walls, gothic line, siegfried line...).
