I believe you can save in “real time” although I don’t know exactly how it works. I also believe that pausing the game in “real time” is VERBOTEN. I think it confuses the server. It would have to be played at slow or very slow, IMO, or it would just be a confusion fest to me. I don’t know if the game is played directly off the Paradox servers or if it’s a host/client deal either.
A few tips off the top of my head:
Always run air missions during the day. Unless your enemy has air superiority in the area and your bombers are being shot up. It takes forever to repair and regain org for air units so don’t let them get wasted for no reason.
Always split your BB/BC’s and carriers into separate battle groups and run subs in groups alone. The AI’s admirals, and your’s as well, will ALWAYS attempt to stay within range of the carrier aircraft but OUTSIDE the range of capital guns and subs, so if you have 1 carrier in a group with 10 battleships/battlecruisers you will be wasting your BB/BC’s. I usually go with 1 Light cruiser(best air defense), and 1 Destroyer(best sub defense) per carrier plus 1 or 2 Heavy cruisers or 1 BB/BC (a few more if the fleet is huge) on the side in case someone’s fleet sneaks up on you at night( carrier’s almost always catch daytime raids well out of range of subs or capital guns, but night raids can be a different story). Always keep your capital ship/small ship ratio at 1/1 or better. If your capital ships(BB/CV/BC/HC) outnumber their support ships(Lt cruisers/DD’s) you take a penalty to combat effectiveness. The bigger the difference the bigger the penalty.
Avoid maxing out an admiral’s or air general’s command max even if you only have one good air general/admiral and the rest are strokes. I can’t tell you how many times I’ve had two maxed out fleets get caught by an enemy fleet in the same sea territory and end up having the more powerful of my two fleets get hit with the over command max penalty. Over command max KILLS combat effectiveness.
If you are playing one of the Axis powers, especially Germany and Italy, make ABSOLUTELY SURE that you are loading up on resources, money, and oil through trade agreements BEFORE the war starts. After the war starts, your trading options get rather limited (agreements with the allies get cancelled and UK cuts off the Med routes) and your overseas routes will be subject to heavy allied convoy raiding. Heavy industry and oil using units can run you dry quickly and I try to keep as close to minimum as I can with “consumer goods demand” so I’m always heavily negative on money from my tech team salaries. I trade supplies for resources, money, and oil. It hurts your production but supplies give you the best bang for your buck. Germany has a huge energy supply so you can get away with trading that for some of your needs.
I also can’t stress enough that you get the research assistant. Losing two weeks or more on research because you chose the wrong tech team can start to add up quickly. I’ll dig up the link later, I’ve got fireworks to watch now.
