Well I just finished the game on the hardest difficulty, killed all the bears, visited all crypts and completed all tombs. See ya Lara until 2017.
I wish there was a greater incentive to continue exploring after you finish the game. Instead of just finding the rest of the treasures and stuff there should have been more side-missions to complete after finishing the main story and a lot more combat/enemies. Combat is the funnest thing for me and I really don't care about achieving 100% just by picking up little collectibles.
Like bih, I need MORE bears, like two in each cave, and enemies infiltrating everywhere.
If I do what other games should I get 
Am gonna pick this up black friday when it is on sale for 35 dollars
