England needs to put more units into Suez. At least half of all of its armor should go to Africa automatically, and virtually all of its newly made armor before 1945
I usually play as britain, but I think that there is already coding that britain sends units to both Norway and the suez unless their under attack, but I agree that the North african campaign could be opened up a bit more. Generally all that seems to happen is that Italy quickly takes over, or if you play as britain you send a bunch of reinforcements and take Libya.
Operation torch or sonnenblume could be a good idea, but a check would have to occur so that it wouldn't launch the effort if north africa is already won or lost, or it just ends up with a dumb AI invasion like seelowe.
But playing too closely to real life events does take a bit of the fun out of it. I mean, operation seelowe never really happened, but it's fun to play as a sort of what if scenario. But more german action in north africa could be something to look at, as well as a possible Italian attack on malta.
Germany: June 1941, spawn 10 armor units, 10 infantry units, 4 howitzers and 4 field artillery in Poland and in Allied Romania, to push in to Russia [Operation Barbarossa]
Russia: October 1941, Spawn 25 Infantry, 5 armor, 4 aircraft in the Urals, with orders to move to the front.
I don't think that giving the germans more units would be a good idea, though certainly placing them before the war in romania would be a good idea. What I often see is the germans advancing from poland to moscow, while the russian line in the southeast advances into romania.
A 1941 launch of troops from the urals is a good idea, forcing the a german player to go for a quick victory over moscow, though if the player is russia it could interfere with the unit limit.
Then again I wouldn't advise adding more operations until the current ones are fixed. Certainly seelowe is broken, as the AI will keep launching more soldiers across the channel even if their no beach head. This stops when russia attacks, but watching them take warsaw when they are supposed to be the ones being invaded is a little irritating.
French spec ops/partisans should spawn every 3-5 turns in France, and on the order of at least 2 of them, and as many as 4, at once. Any tile taken by them should auto-pillage. A similar effort in Russia would be really nice, especially if they focused on taking railroads and railroad river crossings, because those are a pain in the ass to take if you're on the wrong side of them.
I think partisans are already planned. Also partisans in yugoslavia would be good, though I find that greece tends to cling on for quite a while.
