Final Fantasy XVI is a perfect game. The story is well written and thought out, compelling, invokes emotion, and knows when to add humour that will not take away from the tone.
You are immeditately thrusted into the combat so you can feel the sense of what the game is all about from the word "go". All of the characters are either relatable, sympathetic, or hated in some way.
The dialogue is well written, and the voice acting carries the weight very well.
The combat is amazing, it is easy to pick up if you're a new player while also adding a challenge for those experienced in action games, and the eikon kaiju battles were nothing short of epic in different ways.
XVI leaves no loose ends except for the questions it did not answer. You can pet the dog.
The graphics and visuals are absolutely gorgeous, and even though we are not able to touch the water this game hands down has the best water physics out of any game I have seen.
XVI likes to throw cliches at you only to completely subvert your expectation because it knows that you know what should happen, for example; the final boss is well established and doesn't get outshone by a surprise villain irrelevent to the established plot.
And finally, even though there are some moments where visuals frame drop or the characters move like they're in Final Fantast XIV it is completely outshone to the point that it is only a very minor issue that can be made at best.
It's perfect. Everything, down to the last minute details. 10/10 the best game ever made.
