Conquering Greece in one turn at a cost of approximately 200 PPs sounds pretty cheap to me. Especially if compared to the historical cost. I have been told the Axis can be made to pay dearly for this; but I still haven't seen it in any of m games or AARs. If Greece is going to fall this easy than, IMHO, the Rule that Yugoslavia automatically joins the Axis needs to be changed. But I seem to be a voice in the Wilderness.
Since the Axis controls the skies over Greece and have enough troops to project a threat towards the UK I think there are few UK players that will dare to send the whole royal navy to Greek waters to contest the invasion. If you dont you cant stop the invasion and it is a sure thing as long as you build and are willing to spend the landing ships. Even with a normal conquest overland it is difficult to send British aid since naval interdiction is a real thing nowadays. Not like the early days of the game when you could use your transports with impunity.
Of course the invasion will always be easier then historical since the Axis player will use Germans and not only Italians. In my opinion if the Axis wants Greece it will always fall before March 41 and Yugoslavia will always be Axis. one just have to accept that as part of the game. And 200 pps maybe isnt that bad. I am not sure how much a normal invasion costs so I cant really compare, I guess I am just stingy with my PPs [:)].
