I'm at about 70%.
I'm enjoying it overall but god if it was overrated.
First of all the shooting simply sucks, I don't know what's up with the aim system, maybe the game wants you to use mainly the bow or the evade/counter attack system but as a shooter the game sucks and everything is made worse (or caused?) by the input lag. Fighting against the animals attacking you for example is just a pain.
The story is absolutely cliched and useless.
Writing is acceptable during cutscenes but in-game...? Lara can only say "Incredible", "I can do it", "I have to escape" plus different kind of moanings (that btw seem to be closer in this game to how Lara sounded in the original Tomb Raider games made by Core Design, I don't know if it's just my impression).
The NPCs have the sole purpose to give you boring filler missions (the usual open world fetch quests).
The game still has a nice pacing for the main story missions, exploration is good, the tombs with the puzzles are probably the best element in the game, graphics can be great but the boring snowy setting doesn't help.
Overall I don't think the game deserves more than a 8/10 overall and to be honest the 2013 reboot had a far more interesting setting for me with the japanese temples and architecture.
