This is the first and only Uncharted game I've played, and I can say I thoroughly enjoyed it. The main reason why I wanted to play it was because I was itching for something like Tomb Raider, and while this isn't exactly that, it's really good nevertheless. Personally, I didn't enjoy it as much, but it scratched that itch and I've still had a really great time with it. I won't compare them anymore because I don't think they should be compared.

First of all, you technically get two games in one as U4: A Thief's End and The Lost Legacy are two entirely different stories that share some characters, with different protagonists, but identical gameplay. The stories of both of them are really great, fragmented in chapters, and basically linear with no side stuff to do, but as far as storytelling goes, they are emotional, compelling, and very much worth going through. Personally, I liked Chloe's story more, though Drake's is just as excellent.

Gameplay-wise, there's not much to complain about, it's about what you'd expect from an action-adventure. Puzzles aren't bad, never complicated really, but they can feel repetitive, especially in The Lost Legacy, where the puzzle with rotating pieces that need to align is extremely overused. The combat is decent and with a good range of different weapons. You're also not always forced into open-fire combat, you can take it slow and stealthy, and while this is pretty satisfying, there's no real incentive for you to do it that way. Unfortunately, enemies do feel like bullet sponges even on normal difficulty sometimes, but it's not really an issue.
Terrain traversal is pretty smooth, climbing is pretty good for the most part, and the times where I failed a jump or fell off I felt were rarely the game's fault. Running around often feels a little too slow, I found myself rolling a lot trying to sprint, but there is no sprint. Driving the 4x4 around is pretty fun, especially in the more open areas.
Talking of open areas, here comes an issue that annoyed me quite a bit, there are a bunch of collectibles and treasures to find and all that, scattered everywhere, so the game invites you to explore and search for them, however, a lot of the time there is no marked or obvious path you need to go on to progress the story, which will end with you going there by mistake a lot while trying to find everything there is to find and explore, and most of the times, the game lock you in there and you can't backtrack. This gets frustrating very quickly if you are the kind of player who likes to explore everything.

Visually, it looks fantastic, especially in the lower-lighted areas. And it runs pretty smoothly, on a 4 year old, mid-range at the time, laptop, I had no issues whatsoever with the games, on mid to high settings, getting between 45 and 60 FPS at all times, with no crashes or drops at all in my experience.

Achievement-wise put plain and simple, it's a pain in the ass. If you are a completionist and want to 100% this, I'd avoid that cause it's tedious, unsatisfying and plain annoying. There are some fun achievements, but they are few and far between. Despite there being over 100 achievements and the game being fragmented into chapters, there are no progression achievements. What there are plenty of them for though is collectibles, which aren't marked anywhere and are very very easy to miss. Also, other than those, you have a s***load of specific kill achievements that require precise actions and weapons, or specific orders you need to kill enemies in different ways in a specific amount of time. These are just plain unfun.
What helps is that you can replay chapters or even just combat encounters whenever you want, even using in game cheats or aim lock, so you can get most of these done after finishing the game.
