I think most people agree that Seelowe is too costly and not rewarding enough. If you traded all your $$ for ships and all your air for destroying the UK, you’ll still probably lose the whole game. And the conservative UK turtle makes your odds of actually winning the London battle not so great.
You do make a good point Mr. Marsh, especially if you had an airbase in Greece as part of your other plans, you could fly home on G3 and then re-disperse/focus during G4. But as I see it, you can’t really wait that long to enter the war against Russia. Letting it have 4 turns of 37 income turns it from a wimp to a real challenge.
Usually we’ll declare on G2. Under your plan, the planes cant help at all then and are about to leave the area, so probably not going to attack with just ground forces and then show the opponent that your planes are OOP
So if we go G3, we are only attacking a few border territories. Russia may lose 1-2 income. Planes landed.
On G4, you are not able to threaten; Gibraltar, any kind of Sea Lion (so UK, seeing you move off on G2, can spend however it likes), reformed fleets in the UK close seas, Russian backing stacks, the far north, Baltic fleet, etc.
That’s where things get sticky. I like your idea for starting a long(er) game, now Italy has some $$ and you are only 1 (or maybe 1.5) turn slower attacking Russia but you’re kicking butt in Africa.
