Just to throw it out there, what would you guys think of some sandbox/rpg elements in Hitman? I always enjoyed how much attention to detail there was in each mission of the Hitman games so maybe sandbox might dumb that down for the worse. However, I think having a set of complex 'core' missions, just like the previous games and a sandbox/rpg 'coating' could add something. Perhaps you could earn money, effect your notoriety/skill parameters? A little like Assassin's Creed 2 did but keeping the main missions as complex and engrossing as ever.
