I've never been so starved for a sequel...ever. Fuck, I need this game yesterday!
There are dozens of things I want fixed/added in the sequel, but by far the biggest thing that needs attention is the AI.
-Just think about what would probably happen in real life and make it happen in the game. If you casually enter a restricted area, you should be told to leave, threatened, maybe even physically roughed up a bit, but the guns shouldn't immediately come out once you cross an invisible boundary.
-If a security guard or police officer sees you brandishing a weapon, they should tell you to freeze and drop it, if you run, they chase and try to subdue you. Just pulling out a gun and shooting is unrealistic, unfun, and completely unnecessary.
-If you're in disguise,you should be able to actually blend in. In past games, guards could hover over bodies, sound alarms, even drag dead bodies and hide them out of sight, all without raising suspicion. If you try and act out your disguise, it will most likely end in an alarm.
-Use your money mid level towards various ends. Purchase less conspicuous clothing and props (umbrellas, newpapers, containers for bombs or guns, etc.), bribe people for information,services, or access (like paying the prostitute in Contracts to distract a guard), things like that.
-Be able to realistically interact with the AI. Once in disguise, communicate with your fellow guards/officers. Make small talk with the guards to gain their trust, be able to check in to blend in better or manipulate their positions (kill someone report the body, backup arrives, leaving routes unguarded and guards vulnerable to attack).
-Finally, establish a certain relationship between police/security and criminal thugs. In some levels, the police could be very upstanding and law abiding, in which case they might interfere with criminal activities, but if a cop goes lone wolf into a situation with a bunch of thugs, he might get killed. On the other end of the spectrum, the police may be corrupt and in bed with the criminals, making them near inseparable, though money disputes may damper their relationships. In other cases, the non-cop guards are more legitimate and just serve as body guards to a corrupt target, they could possibly aid or call the police if they have a hard time. 47 should have a way of discovering these types of relationships and use them to his advantage.
