I don't think the world is completely open, but from what I understand, groups of missions will take place in the same area. You'll have a camp and an area to explore between missions before moving onto another section.

The swimming thing is news to me. Completely sucks if true.

hmmm..meh

I actually disagree with most here. I dont know if what was said in the OP was true and certainly I would prefer it not to be, but regardless I actually like the new changes. I have played the Tomb Raider Trilogy and the only game I liked was TR Legends which is the only one that features a good mix of fighting and puzzlesolving. The others were more puzzle oriented which I did not find fun. So I generally like the new changes - they seem to be trying a new mesh of Uncharted style action and older TR style puzzles and exploration and if they get it right I think it could be great. I am pretty excited for this game on evidence so far.

Well i dont have the feeling Uncharted is like watching a movie. You have a lot of opputurnities to kill your enemys. The only think is that Uncharted is very linear and has a lot of animations ( one of the reasons why some people think its like watching a movie)

And from what i have seen from Tomb raider its very uncharty which in my eyes is no problem since i liked uncharted very much.

Naughty dog was very clever in uncharted 2, they were able to blend everything seamlessly that it still felt like a game. Uncharted 3 not so much, especially in the burning chateau where it was crawling with scripted events.

My impression of tomb raider is that the majority of the game will be heavily scripted, hopefully they dont over do it. fingers cross

I think it's even worse: games are mostly too easy. I remember me playing Tomb Raider 1 on Sega Saturn and it was a disturbing experience at first. The levels were gigantic, there was a lot of platforming, enemies were hard (because of controls also) and save-crystals were as rare as health-packs. There was one level where I played a whole week to finish it! Nowadays games show you which switch to activate (then why is there one?!), the levels are linear so you can't take the wrong direction... Everytime you play you get "forward" - there are almost no frustrating sequences. Sure, this gives players a feeling of success but I think some things could really be more challenging - enemies and level-design.

Of course not all games are like this but the very popular ones seem to fit in my description.

everytime i see this game the graphics get worse. 

well i wanted big open puzzles and searching for treasures but that went out of the window a while ago,as long as they have one in there somewhere,

The game looked like it focused more on cinematics and set pieces right frmo the start. I'm not expecting much exploration.

Screw you guys. Day one purchase.
