The main advantage for overall game balance in AA50 1942 (Allies v Axis) under these rules (with the non-com opening), is that the US gets to keep their Pacific carrier deck. This is fairly major in encouraging the dual theater war, and is one of the things we like most about the set up. The bonus structure also encourages a more effective Russian tank purchase under most set ups, which leads to a dramatic Kursk style scenerio on the eastern front under most openings. Japan alternatively has a much greater incentive to build air and naval, because the Allied position on the sea is stronger, requiring a more substantial counter.
Also, and this is just an aside, but having played quite a few alternative starts now, it has become much clearer to me why the gameplay on this mapboard is so centered around Moscow and Europe. It is a consequence of the basic map territory connections. 7 territories border Moscow which mean 7 ways in, a split 7 defense of the capital. Berlin is 5 territories and a sea zone, 6 ways in, 6 split defense. UK is 5 all from the sea. Compared to Eastern USA and Japan which can both be defended from a single sea zone, it is fairly clear to me why the board would favor KGF, regardless of the unit set up, or the starting income conditions. And why Moscow is the clear choice over London, for a conservative Axis warplan.
Still, that said, I do find that the bonus scheme outlined above helps to moderate the built-into-the-board drivers on Moscow and Berlin (and to a lesser extent London), and pushes it instead into a somewhat more “world” wide conflict. Plus the idea of a board which features 6 possible starts rather than just 1 seems to me a worthwhile thing to pursue. At least 6 times the replay, but much more in actuality, since the bonuses allow for so many potentially different purchasing strats.
