I think my issue so far, play wise, is that it doesn't seem as complete as Tomb Raider Legend was. I finished that game, and aside from the usual running, climbing, shooting etc, it had nice puzzles in it. Stuff like put an object on one side of a seesaw type environment object, drop another object on the other size of the seesaw to hurl the first object to where you need it to be. Or the grappling hook which you can launch to grab a moving platform thats far away and pull it to you. Basically, puzzles where you can interact with the environment to solve a problem, which is what I thought made Tomb Raider Legend so cool. Maybe the final game will be different, but from the demo is seems like Uncharted will mostly be just climbing and shooting, kind of like the old Tomb Raider games used to be.
