@Magro That’s not an entirely fair comparison. In G40 games there’s plenty of opportunities early on where one side or the other can get diced out of the game (Paris, Taranto, attacking the Yunnan stack, etc.) by taking more casualties than you statistically should as Axis.
The main perk for G40 over AA50 is that the massive size of the board allows you a bit more freedom in deciding your strategies (UK Factories in Middle East Vs. 100% of income into Fleet, trying to send Russians to various parts of the map to steal cheap NO points, etc.), but the big picture is still pretty static (European Axis can-open their way to Moscow, Russians turtle, Japan does either J1 or J3 and crushes Calcutta/Money islands to wrack up a huge IPC income, US/UK attempts to build a surface fleet to retake Africa/the Middle East + Pressure Germany).
AA50’s perks are that it has a lower bid than G40 (OOB, anyway) and the game is quick enough to be played in half a day or so.
