I want the heads of my enemies on pikes in my QuartersI'm actually legit hoping for little trophies and souvenirs in the captains quarters, a la Mass Effect (and plenty of other games).
I can't put my finger on why exactly, but I really enjoy games where as a side effect of the main game you make your 'home' change and evolve. My favorite example is Monteriggioni in AC2, where as you come back from your murder sprees you can sink your money into practical upgrades and swanky renaissance art. Adds another feeling of accomplishment.
