A few reccomendations for those of you who just got the game to get maximal enjoyment.
1. Redefine what setpeices mean to you. The bombastic in your face set peices exist in this game, but the bulk of the new set pieces are there to impress you from your environments, interactions, and the jump into an all new world. In short, if your waiting for the next thing to go "boom"- this won't happen nearly as often. However, if you play the game with the intention of- and this might sound redundant- exploring or CHARTING the world- you will find youself blown away.
2. Do not marathon this game. Uncharted 4, is similar to the Last of Us in that it asks you to take a step back, recollect, and take inspiration from your environments, encounters, and actions. An 8 hour session will just leave you fatigued because you are consistenly exploring, learning about characters, and finding yourself solving another puzzle. This a 16-20 hour game- the legnth of two seasons of your favorite television show. You cannot, no matter how commited, fully appreciate something like this with an intent to finish it as fast possible.
3. Readjust your definition of the franchise. Uncharted 4 is more ADVENTURE than third person shooter. In fact, a majority of the game is spent absorbing the environments and invoking the sense of discovery. That sense and wonder of reliving history is unquestionably the strongest point of the game. Previous Uncharted games would throw you into combat with wave after wave of enemies, however this game does away with that for far more thoughtful, directed, and well designed enemy encounters. There is less action, but when it's there its infinitely better than the previous games.
4. DO NOT play this game on the hardest mode on your first play through. The medium setting is hard enough, and frustration will kick in because you'll want to find out what happens next but can't seem to defeat the current wave of enemies. This is a testament to how well designed the AI is, and how the game asks you to approach a situation. Leave the ultra critical thinking to a second play through.
