I just completed the 4th game and I'm just in awe. I remember having to force myself to finish the first one because I wasn't entirely invested, but by the time I got to the fourth one I had to force myself not to finish it all in one go so I could savor it. Crazy how time changes things.
An amazing series, and I felt like it only got better and better with each new game. Would love for them to make a fifth one (though I still need to play The Lost Legacy even though I doubt without Nate's narrative I'd enjoy it as much as I mainly love games for their stories more so than their game-play), but I think the fourth one was a beautiful finale to an incredible series of games.
Also makes me want to re-watch the Indiana Jones films which is amazing considering I was never a big fan of them, but now think I'd have a whole new appreciation for them. Awesome stories, amazing mechanics/graphics (Jesus did A Thief's End have some beautiful imagery, I can't even count how many times I hit the screenshot button on my PS4), and really exciting set pieces.
It's tough, but I'd probably rank them as so:
A Thief's End. Drake's Deception. Drake's Fortune. Among Thieves.
The fourth one is probably in my top five games ever, but the other three are no slouches and are so neck-and-neck with one another that they could easily be flip-flopped around and it wouldn't matter. Might have to buy The Lost Legacy just to quench my thirst, but I think I'll replay Last of Us first.
Only played the first two. The first is pretty bad, honestly. Feels like a half-assed Crash Bandicoot with none of the charm. The second game fixed all that, making the action really seem cinematic (that train fight!!!) and much more enjoyable.
