"Cops and Robbers, and Thief vs Thief," Schatz replied. "We wanted to add two additional competitive game modes to the game. We got them to playable, but we discovered that for both modes the balance didn't really work within the existing levels."
Thief vs Thief had players compete in a single stage, to see who could collect the most coins, grab the trophy and get out first – but the player who left the gate first had a huge advantage, sucking up all of the coins, and the mode didn't turn out to be as fun as Schatz had hoped, he said. Cops and Robbers added a police officer to every level, but the early stages were too easy and the later stages too difficult.
With some tweaks, Schatz said he hoped to bring Cops and Robbers to Monaco "at some point," possibly as DLC.
Monaco's characters evolved along with the gameplay, and Schatz described how each of them spawned, early in development: "The Gentleman used to be a hypnotist, The Lookout used to be the Prowler (parkour expert), The Mole used to be The Muscle, The Pickpocket used to be The Rat (could rat out teammates to save himself). The Redhead had a taser or a pistol at one point. The Pickpocket started out as dwarf twins instead of a man with a monkey." Stranger things.
Once Monaco's final touches were all settled, Schatz said he had an idea to develop a "good console RTS (or at least simple-controls RTS) that is as strategically as deep as the competitive RTSes." First, he has to work on the Monaco level editor, expansions and maybe more ports – he singled out Vita and PS4, while Mac and Linux ports are already on the books.
