There are many aspects you mentioned that sound interesting: evolving camp / base, recruitment, movable camera, positions and combos in battles, convictions and the branching story.
I am especially curious about the consequences of choices too. And I once read that there may be variables in the story depending on how well you did in key battles. I hope that's true as I'd definitely enjoy repeating a battle over and over until the best outcome is reached :D
