From Alrik:
"What I'd find interesting, personally, would be for example to have a different ally depending on my choice. Or in another part of the land things dvelop differently because of a decision (the hero decided, for example, to go to a certain, distant battlefield to fight against enemies, whereas on a different battlefield the hero decided NOT to visit, (probably other) enemies win because of the hero's group not being there. Or even so that the hero's group can be splitted between both battlefields: In both, then, the enemy's troops have become "lighter" because of the hero's groups' effort, but they haven't been completely eradicated)."

Interestingly, I've written a convo scene for the game which does precisely that; make you decide whether to go to one area, another, or split your forces. This can affect not only the outcome of a battle, but your party relationships.
