Same here, I've gathered all the collectibles just to see the whole map and secrets. I maxed everything at the end and had some points left I think. Those samurai ghosts were dropping like flies and I was using only my bow for most of the time.
The most tiresome was navigating throught the wrecks near the sea and finding the mines and letters. Tombs were too easy, and it was a sloppy nod to the roots of the series. Very good port, even on my prehistoric rig it worked for the most time like a charm. Not with all the high settings, but whatever, it looked good enough. The game felt like a weird mix of Rambo and The Descent (probably due to the dark palette and all these dark places that we visit, plus gruesome death animations of Lara).
PS. Lara has the best booty in the Underworld part. That swimsuit !
On the downside, my laptop was basically a fireball after playing for an hour or two. I think it eventally crashed the game from overheating in the very final level (though it happened during an autosave, so perhaps it was just a regular glitch). That's gaming laptops for you.
