The beauty of FFG's expansions is that they often add little rules and units to the base game that make the game that much more interesting. Like the AT guns in Days of Fox, or destroying structures in Normandy. It's these little touches that make the game better and better with each expansion. Also, apart from whole armies, adding a few odd units in each expansion also raises the value of the game, like the aforementioned AT guns.
What small rules that are added to the base game during gameplay would you like to see in the next expansions and what units would you like to see added in the expansions as well? These rules and units aren't directly related to the expansion's theme itself.
. Otherwise it is only a matter of having a bigger table (unless you play on a floor [with more than 12 map boards])
Also , who died and made you the boss of Me???
