I really enjoyed this game. I wish it was longer though. The game moved really well, combat was smooth and fun. It just seemed like everything was about half as long as it should be. Tombs need more content. The writing was really well done. I had to give it an 8 simply because it was shorter than I would've liked it to be. A must play.
The combat was fun, traversing the island was fun but after you take out dialogue, cut scenes, QTEs and set piece events you aren't left with much actual game. This becomes doubly harmful for this particular game because there is no option for NG+, when you are finished with the story you are left on the island with next to no enemies and just generally nothing to do.
I really wanted to put some more time into the game but there isn't anything that interests me left to do. If you're not into looking high and low, playing find the tiny hidden GPS cache, after you've finished with the tombs there isn't anything to do really. Actually playing time was probably about 7 hours on hard difficulty w/ finishing all the tombs. 15 hours if ya include all the down time.
