I am on Chapter 8 (I Googled, and it says that the game is 11 chapters). The game is "good" but not nearly as good as previous entries. Very little action, and the dialog between the two girls is funny and witty at times, but doesn't click with me the way it did with Nathan Drake and others from the previous entries. One chapter I ride around an elephant, one chapter I drive around a jeep in a semi-open area with nothing to do but look for tokens, another chapter I aligned some shadows. Seems like I encounter about 5 enemies in an area, usually a long time before I see any. Seems there is like 1 puzzle per chapter?
Animations, lighting are all top notch and some of the best in the business IMO. Textures, as usual, are too glossy/cartoony. Could be me, but it seems the faces are more realistic in this Lost Legacy than they are in UC4, even though it's the same engine. Maybe they had a chance to make a few improvements.
Looking forward to finishing this, but in no hurry for another Uncharted at the moment. They need to revamp the series, it seems a bit stale with this particular entry. Odd considering, UC4 was the best of the 4 IMO. I loved the Nathan/Sam interaction as much as I loved Alan Wake/Barry interaction.
