How "open world" is it really, though? If TPP was split up as a bunch of separate areas that were GZ camp in size, or bigger, is that different than the areas in MGS4, for example?
In MGS4 you had a bunch of separate areas alá Monster Hunter; whatever you did in one are didn't necessary affect the other area.
In GZ it's one huge camp where everything feels more connected - if you put a enemy to sleep and didn't hide him well in one area of the map, it might bite your ass later and trigger a search for you. Also, you have guards roaming around and sometimes vehicles come from out of nowhere to find you.
While I agree that some of these elements can be found in MGS4 to some degree, it all feels different because it's one big area in GZ and there was more random GTA-esque stuff happening to me in GZ than in the entirety of MGS4.
I can just speculate about TPP, but here's what I expect: from the trailer, I think it's safe to assume that you will get send to different parts of the world just like in MGS4, but you will always have one big map like in GZ. The red band trailer of TPP shows Afghanistan and the are is muuuuch bigger than GZ, and that's where your mission takes place. I just wonder if they'll use one big area per mission or many missions in one big area.
Oh, is this supposed to be humanistic behaviour per guard? I thought it was based on movement and distance, like if you were kind of close and moved a lot or if you disturbed them repeatedly they'd commit to checking it out. If it was a slight movement from far away and you didn't alert them again they wouldn't care.
Yeah, I meant the humanistic behaviour. The view range of guards can be seen as a con of the A.I., but other than that I was satisfied with what we get and I must admit I've just played on 'normal'; I assume the other difficulties in TPP will make guards much tougher and smarter
