An idea for a game

[Bridge]

Kill a person and his body will stay there and stink up the area, attracting hungry monsters and repeling humans. It can be moved, it can be eaten, it can be used as a decoy, a weapon, a shield, a platform to stand on, etc. And the same goes for inanimate objects. Nothing just disappears, or becomes just another part of the scenery. Break a glass and you can use the shards, tear off an arm and you can use it as a lure,or a club, or a doorstop. Every animate object is a complete character, with it's own physical appearance and state, it's own psychological state, it's own intelligence level, it's own set of information it knows, and it's own possessions. Object don't disappear or stop moving just because you are far from them or can't see them. The world goes on whether you are there to witness it or not.[...]
The city guard are capable of complex plans, and have near-perfect order and discipline.[...]
Psychology plays a large role in the behaviour of both individuals and groups, and can change based on positive and negative reinforcement[...]Information can be conveyed through various media. If a character knows something then that piece of information will influence or determine the actions of that character: change the array of possible solutions to a problem, causing him to perform a mission or give up on it, adding the possible mission or ruling some out, etc. Depending on the character's intelligence level, he could take various pieces of information, put them together, and as a result derive new information from it.[...]

Ok now I don't mean to be rude, so please don't get this the wrong way, but...umm...you've never actually taken part in any kind of game development, have you? Because these are exactly the kinds of ideas Peter "Crazypants" Molyneux used to have before the people tasked with actually MAKING the game for him had to drag him back to the harsh reality. Seriously, to reach such a level of interactivity and AI complexity in your game while also creating a huge world, thousands of NPCs, a compelling story, quests and whatnot, you would need a team of about 1000 professionals, working for 20 years straight without ever being allowed to see their families. And it would probably cost more money than the next Avatar movie.

That's my feedback for the technical side. Can't say much about the story (I'm no good at writing myself) other than that it sounds vaguely...generic? o.O

Oh and yes, Gothic 2 is one of the best games ever

Yeah, it's unfortunate but you have to realize one thing: computers cannot think. They can only do what they are told to do and so NPCs in video games cannot truly deduce. If it appears an NPC has deduced something from the way you act or from events that occurred before it's only because someone "told the NPC" (not as simple as that): when x happens, this piece of information will be known to you. Realistic AI is the result of many days of thinking of absolutely everything that can happen and creating a complex tree of suitable "reactions". It's very time consuming and difficult which is why not many games have good AI.

Even with all the flak they gets, MMOs really are the perfect gaming experience in theory. If people would be more serious, and if they were designed differently, MMORPGs would be incomparably superior to SPRPGs. Why? Because there you have actual non-artificial intelligence that can react to any situation and even simple game mechanics can offer an intricate and dynamic experience. Alas, as with any multiplayer platform, people are prone to metagaming and not taking anything seriously which really detracts from the overall experience. MMO developers realize this and place less of an emphasis on role-playing and more on grinding out XP in an efficient and fun manner and socializing.
