Well this remember me when i try a napoleonic mod using 1.01 version...
To be a 1.0 version PzB has a good engine but sure needs improvements, for example in air attacks i think needs affect the hex, for example, if you have in same hex 3 counters, 1 with 1 tank other with 6 tanks and an infantry stack the attack needs affect all them, not as is now killing the smaller tank stack.
Maybe the problem with aircraft VP is that they are more usefull in airfields because use them you are going to lose VP... for me many units needs have 0 AAA value, specially in tank units because not all have AAA MGs and well, shot down them with guns is hard... maybe the air units that do flat attacks (i think in IL-2) need a penalty when attack tank units because tanks can engage them.
Waiting the first patch... maybe is coming with a new brother for Kursk???
