I have played (in the middle of my 3rd game, so take it for what it is). I have been Axis all 3 games because my friends refuse to let me try being the Allies until they are able to beat me. I have found that building for Sea Lion turn 1 is great because it has so much versitility but not worth pursuing unless it is feasible to make UK fall turn 2.
Game 1, succeeded in turn 2 Sea Lion they quit because they thought it was over.
Game 2, built Sea Lion they bunkered and I went over to Leningrad and was putting the smack down on Russia while using a paper navy (subs and bombers to destroy UK’s navy everytime they tried to build one). Just out side Moscow when cats destroyed the game but bascially Russia was about to fall and US was dumb and went down to the Medeterranian but lost all land units so just sat there so Italy could build no navy. Italy built a IC in Egypt so it was pointless.
Game 3 was a fluke/unwise tactics by allies (keep in mind I am playing with the same people). I built 3 trans and 1 cruiser and a few artillary turn 1. Decimated UK navy (my teammate did all rolls with spactacular rolls the whole game so far). UK brought units from Canada, pulled 2 infantry to Scotland, lost 1 fighter destroying my battleship (so had 7 units to defend capital, I couldn’t believe it was so undefended after I did it once already!). I took UK round 2 only losing 1 bomber (stupid lucky AA roll on his last roll) and all infantry, had 1 tank and 2 art left. This game is basically done because my teammate’s rolls were insanely good. We took burma road country (forgot name) in Jturn 1. China tried to take it back and my teammated lost all his units but took all of Chinas so we just moved all we had into it even planes and UK is scared to attack it. China has 5 pieces of land left soon to be 3 and can build nothing basically. UK pacific is getting 8 ipc a turn and no navy, another spacticular defense of our navy near india were my guy rolled 5 2s in a row decimating attacking force of uk med navy, pacific navy (minus battleship, we took that out turn 1), and all of pacific’s airforce. We are about to make ANZAK lose its capital because they left it defended only with 2 inf and a carrier outside while I have 1 inf 1 art and a big portion of my navy in attacking distance (2 carriers with 2 planes and to tac). This is all before round 3!
