Truly Simultaneous Battles: Neither Side Strikes First
Every turn in GENERAL! is meant to resolve all at once, and now melee really does. Before, fights were worked out one by one with your army first. So a formation you destroyed never got its own blow in, and several close calls quietly went your way.
Now every clash is worked out from the same moment and all losses land together. A formation destroyed this turn still hits back.
Ties are settled fairly too:
two formations charging into the same gap meet where they stand
two formations heading for the same tile are decided by the shorter march, or a fair coin toss
pulling back from each other costs both sides their free strike
Two identical AI armies used to win 138 battles to 62 depending only on which side they played. Now the battles that end with a winner split evenly.
