I just hammered out a fucking novel on b3d. I'll post it here to:

I got Metal Gear Solid 4 at a midnite launch and started playing a new game on Big Boss Hard. I am now almost done with the game. I've played over 30 hours. I am playing with a whole lot more restarts and deaths than the average player. I have been trying to make it thru the game by any means possible. It really is very difficult. Here follows my impressions of the AI.
I don't play any PC games, so I can't speak for the AI in those games. But among console games, MGS4 is the best.
I should mention this... during my ramblings, I won't spoil any specifics but I may hint at an overarching revelation about the game that was gradually revealed to me by the game itself... becoming obvious by the fourth act. It's vague.... but if you are interested in my take on the gameplay I have to share it with you. I'm trying to say that if you think that taking the game apart a bit would spoil some of the magic for you then you may not want to read on.
So every scene in the game is a self-contained setpiece. Maybe people playing thru on medium see them strung together, but I and dying and retrying even the easiest one 5 times. On many scenes, I lose count of how many times I die. Spending 3 or 4 hours to get a 20 minute suscessful run of a particular scene is not uncommon at all. There are hundreds of individual scenes, each different from the last. These scenes are appearing from my perspective, like linear levels of games back when they where balls hard. Each scene is devious.
Now what makes this gameplay so amazing is that the scenes are each self contained evironments, whi th AI units dropped in and patrolling, or fighting, or doing whatever. When a scene starts, the enemies are simply let loose into the environment, and completly run by their ai. This creates a little playground for you the player to excerscise your skill complete to your own satisfaction.
Not unlike Mario Galaxy.... A quantum leap in an established gameplay mechanic (the one it's predesessor invented) followed by brilliant level design that thouroughly explores every nook and crany of that novel new mechanic. In Mario Galaxy 3d platforming was spontaneously evolved into variable-dimensional platforming. Here in MGS4, stealth gameplay is evolved into a live and dynamic deception.
Here's how: Each individual unit in the game has an ai. The types of behavior units exhibit in this game are staggering in their variety. Most of them are very complex. By complex I mean that they have a very large number of possible actions, are able to communicate to one another (some via network. try beating back 20 frogs on Hard!) and as individuals, are largely unpredictable. Now take two big handfuls of ai soldiers and throw them into an exquisitly designed 3d antfarm not unlike something out of Mario Galaxy and see them crawl around and patrol the place of as they see fit. Or set them to fight against each other. Or swarm in on the player in coordinated waves. There are so many eniemies, all behaving so intelligently and richly interacting with each other and the player... On the large scale that the game regularly achieves, a pattern emerges, and the behaviour of the game world is actually predictable.
It's a testement to the game design that almos every time I've been hung up on a point-to-topoint scenario, the solution that ended up working for me was total stealth. Even at this stage in the game, where I can afford every nasty weapon on offer, none of them has been enough to blaze thru most of these scenarios. After dozens of attempts trying to shoot my way thru a real funhouse in act 5, I took a break, then sat back down and did a slow, quiet sneak. Getting this far on Hard has forced me to get to know the behavior of Frogs. And how that is different than Elite PMCs. Did anyone else notice that Frogs communicate really well with each other but not with any other units? I've had to keep that in mind along with every other bit of knowledge because this game is really hard! This is way at the forfront of stealth and action gaming.
In fact, I thkn this is actually the unification of stealth and action. It's really just and action game now. It's just one that takes into account the enemie's level of awarness to such an awesome level. The fact that I can just jump into these amazing set piece levels and do whatever I please to meet the objective. It's jsut a matter of getting to know how these little bastards think ;D ...
What got me thinking about this was reading comments about some of you simply blasting thru scenes having failed the steal route. Try playing on hard mode where enemy reactions outpace your own. Can't just shoot your way out of everything.

I know, huh?
