I haven't finished the game, but so far, so it's very good.
The game looks amazing graphically, in fact, the PS3 shines thoroughly here in the way it creates exact shadows, and matches the characters mouths to the voices so you can almost read their lips. When Nathan takes a swim, his clothes darken and get wet and change appearance to show it. When Nathan gets out of the water, the clothes remain visibly wet. Not important at all, but an incredible bit of attention to detail. The old ruins explored in the beginning are gorgeously crafted and you can really feel the deep, dank, musty feel that they have. In the lavish jungle, the trees, plants and everything on screen keep an amazing frame rate and the visual pleasure that this game creates is utterly everything the PS3 is all about.
I haven't played through the game yet, so I'm a bit unfamiliar with all of the levels. The ones I have seen are not terribly long, so I don't think the game will take terribly long to finish. I hope that I am wrong, as I'd love to get further lost in the game play and story line that gets established right from the jump off. So far there have been traps to avoid, puzzles to solve and pirates to shoot at. I get a real Indiana Jones feel to the story. The game play has had me climb levels, swim distances, find treasures, swing on vines and all out become an adventurer, which makes the game feel a bit like Pitfall if it had been made twenty five years later.
Overall, I can only recommend this game so far. It's been an amazing journey and I've only just begun it. I'm usually much more biased towards my 360, but in this case the PS3 has been used perfectly to compliment what I consider one of this year's great games.
