1. Yes, you can launch fighters to protect your factories however sometimes the AI makes questionable choices, I am guessing to protect its fighters against a Sea Lion
2. Not too sure about this, I never done a before G4 with the Axis but I am guessing bombing the hell out of USSR is ideal.
3. The Red Navy is basically useless here, I mean most USSR players don’t even deploy it. Unless you’re going to build a large navy for the Kreigsmarine, you can basically ignore it however I have seen Germany bomb it out just because.
4. It depends on your long term goal with Japan, I am getting to a point where I am no longer seeing China has a threat to the game however I do like to shut down Burma Road because it helps deter UK ironically.
5. Mongolia works like this, if Japan conquers a USSR boarder territory, they join USSR at the end of whoever is attacking boarder territories turn. So if you attack Mongolia the same time you attack USSR, your legally attacking a neutral. However, if USSR attacks Japanese territories, Mongolia “breaks” their alliance with USSR and becomes a strict neutral. China plays no role in this rule.
6. No, in G40, it is worthless to buy research tokens because the cost is wasted when you should be building a military, only two nations have the income to spare for it and even then, I don’t do it. USA due to being a rich nations and ANZAC if you’re making enough money to out produce your small factory.
7. Turkish straights is controlled by Turkey, NOT Greece. Second, no one really knows what to do with Italy due to them always taking it from UK right from the get go. So depending on UK fleet movements, you can either can open for Germany or focus on Africa.
8. J2 builds I can’t answer simply because I do one of two attacks, I either build up ride US trade and strike at J4 or I open hell’s gates and declare war on everyone with the exception of USSR and conquer everything; bomb Pearl Harbor, take over the Phillis, conquer France Indo-China, conquer Hong Kong, drive deep into China and then build a third fleet so the other two can focus on taking over Dutch and UK territories.
