My copy arrived this morning so I've played some of the game.
So far I'm loving it. Its a beautiful looking game, very cinematic. The GB guys sure werent kidding though about graphic deaths, I got crushed by a boulder quite early on. I also agree with the complaints that ive read about the UI popping up at terrible moments. The game is so cinematic that when you are looking out over the Island or the ocean but suddenly get a tool tip about XP pop up it pulls you right out of the moment.
Loving the bow, if I can then I plan to use that most of the time in the game I think. I dont usually like stealth in games but its working nicely here.
Lara as well is really well done I think. I enjoyed the first 3 Tomb Raider games but never really cared about her one way or the other, she was just a bit too larger than life. They've done a great job humanizing this Lara though.
I may have just not been paying proper attention but it does feel like a bit more explanation could be used on things. I still dont know when its saving the game (I assume either when I stop at a campfire or just at certain moments) and I had to go ask on Twitter what the point of hunting animals was.
Overall though a great first impression. Cant wait to put more time into it.
