well... let's begin with a few units
standard riflemen for every civ
(better) paratroopers for the US, UK
u-boot for the germans, bigger range and attack perhaps
a landing vehicle of some sort which allows every unit in it to land like a marine but with an attack penalty(when they did landings at omaha etc these beaches were being heavily guarded, but they broke through eventually)
spitfires for the UK
zeros for the Japanese
stuka divebomber for the germans (not so good attack and defence, but a great bombard value)
some kind of jet fighter for the germans, i believe this one was just not produced because of problems with the factories and hitler stopped funding the program. Should be available with some kind of late game tech)
better defence infantry for the japanese
V2 missiles (immobile, can only be built at a city which has a certain improvement)
tiger tank for the germans (better attack, defence)
shermans for the US (worse stats, but a lot cheaper)
ss stormtroopers for germany
commandos for the UK (and US perhaps)
better (faster movement perhaps) tanks for the russians
better naval units for the UK
b-52 bombers
some kind of coastal fortress that can be built on any coastal tile, not just in a city
resistance in a city which has been captured, which the original owner can control (like when a city is taken over, a spy is automatically planted in it, which you can use for info gathering, sabotage, and such)
railroad should be removed. we have train stations for that (read below txt). They are too much of an advantage for the germans (who can defend with all their units on both sides of their area at once) and for the USSR, who can move all units they produce to their front lines at once
train stations should replace airports. Most transport was done by trains there, and this also solves the problem that railroad is too much of an advantage for a nation which is under attack.
The only problem i see is that you might not be able to let a train station work like a airport, but only on the same continent
no or hardly no cultural takeovers. Not logical in such a short timeframe, and not logical if a large german city revolts cos they just love the english so much
submarines have a bombardment abilty (they also have that in my mod, and it works great), but can only target ships
destroyers can see subs
fighters can see subs
bombardment can kill ships (sea, air AND land units. the land bombardment units would represent the coastal defence, which they also used artillery for a lot.
now my inspiration has run dry for the moment, so someone else may continue on these ideas
<edit>
btw, what do you think is better??? a whole earth scenario, or 2
(europe and pacific) seperate ones??
with one big you get a more realistic game, the bigger picture, with countries needing to defend their colonies and supply lines, cos what if the germans managed to keep blocking the supply lines from the US to the UK with their subs, perhaps they would have won the war then.
The problem is that you get a less detailed map, and less detailed battles and such. the ardennes will for example be only 2 or 3 terrain squares, and the channel will be 1 or 2 coastal squares, which doesn't really allow for a naval superiority there (and also abuse, like the germans dumping 1 battleship and 2 destroyers in the channel, and effectively blocking the english fleet
buildings/wonders/improvements/misc:
forced labor camps: increase production, decrease happyness ??
manhattan project, allows only the civ who built it to build nukes (small wonder)
nukes (should be an air unit, more like a bomber converted to carry nukes, still a one shot item, but at least now you can intercept it with AirSup (which is logical IMO ). Should be pretty expensive.
something like theatre, cinema, to keep the pplz at home happy (which happened a lot in the us, especially during the early years of the war, even though the US was involved (sort of))
should leaders spawn during the war, or should we just give every civ a few leaders to start with, and they have to do it with that. The last option seems more logical, since we are going to do a pretty realistic scenario, and to keep it a bit balanced
leaders can only create armies, they can't rush wonders (this should be obvious).
different defence bonuses and penalties for different units and different terrain (did you know btw that you can give a negative defence penalty to terrains?? can be pretty useful)
what i mean is that infantry defending vs tanks on a plain should in favor of the tank, but infantry defending vs tanks in a mountain should be very much in the favor to the infantry. If it was tank vs tank in the mountains they should both have about the same chances though (simply stated, tanks get a penalty in certain terrain (and a bonus in others) , and infantry get bonuses and penalties in certain terrain. You'd have to do this for every unit.
also, perhaps, certain units should get bonuses vs other specifical units, destroyers or subhunters getting an attack and defence bonus vs subs, fighters a HUGE bonus vs subs, infantry getting a penalty vs fighters, etc etc.
allow (certain) units to shoot back at air units when they are attacked
allow fighters to escort bombers, so that when a fighter intercepts a bomber, it starts combat with a fighter, if it survived it starts a fight with the next fighter, until there are no fighters available, then it can attack the bomber (or perhaps it just attacks a random unit every time so that it's not certain that it will never attack the bomber, it's just that every fighter added to the escort will lower that chance)
this would require you to group air units, should not be really hard (i hope

)
allow leaders to form armies from ships
let units in armies keep their specific abilities (like seeing subs, carry units, blitz, etc) except a few (like paradrop, treat all units like roads(for obvious reasons) The abilities do NOT apply to the entire army then, but only to the unit. So if you have an army of 2 tigers and one infantry, the army would have blitz (but only when the tanks would be attacking) and when the army was attacked by a fighter, the infantry could shoot back at the fighter (presuming infantry has AA capabilities, would possibly another unit, but just to make it clear)
