U2=U4>UGA>U1>U3
Really weird list for me.
Uncharted 2, at the time, was a masterpiece and the only game that has come close to that for me was Uncharted 4. Not as well paced as U2, but I thought the overall quality was better, especially the ending.
Golden Abyss gets a bad rap, but man, I remember being absolutely blown away by this game. Played it day one and that game alone made the Vita worth it for me. Not only that, that game has my favorite Drake and Sully moment in the series for me.
Uncharted 1 feels like a first game in the series and admittedly each game has surpassed it in quality, but this game hold a special place in my heart for being such a fun adventure that still feels the most focused.
Uncharted 3... Man, Uncharted 3. Not a bad game, but incredibly disappointing. Played it day one (pre-aim patch) and hated, hated, hated the encounter design in that game. I remember "The Settlement" chapter almost making me quit. Not only that, the set-pieces, while good, were no better than U2's. Hell, some were even lifted from U2. I haven't played it since I originally finished it, so I might feel differently once I finally play it again, but as of now, disappointment is the thing that holds this game back for me.
