Well, I finished it with 67%. I have no desire at all to go back and find gps things laying on the ground, or to complete any of the "challenges." I'm done with this game, and most likely the series which, I suppose, will be good for the people who constantly bitched about me being critical of the game, or said that me and people like me just didn't like change. I don't post in threads about games in which I have no interest, and if the series continues as this game does, this will be one of those games.
I really enjoyed what I estimate would be about 1/4 of the game, was actually pretty decent. I enjoyed myself. The platforming wasn't challenging, but satisfying in the same way I find Assassin's Creed satisfying. Traversal rather than platforming, and looking cool while doing it. I enjoyed the verticality of the combat, the freedom you had while fighting.
I did not enjoy the "tombs." The artisitc direction around them was great. It feels like a real missed opportunity to have them expanded on, add a few more environmental traps (were there any traps in this game?) and puzzles. I did not enjoy the lack of challenge. I had my bow upgraded, but for the most part did not bother upgrading any other weapons. I never got the scope on the AK or whatever, so I didn't get to see how broken that was.
I don't care about stories in games, so that was neither here nor there for me. It didn't factor into my enjoyment, or lack thereof, at all, except for the on rails sequences which forced me to play a certain way and took away player agency.
Pretty much everybody else has said exactly how I feel already. I think this game was like junk food. It's the Michael Bay movies of videogames. Fun for the ride but shallow when you try to analyze it. Extremely average game with extremely exceptional presentation.
Edit: Aww, top of the page.
