To me it felt like the sort of improvement i would naturally expect from a game releasing X years later on a more powerful hardware. It was mostly honing, polishing and tweaking the framework of the first game.
Thus, i was left utterly disappointed with its gameplay. It lacked ambition and was too self-content in just being a much more mechanically competent TLOU1.
TLOU2's gameplay loop gets very repetitive and almost nothing is attempted to mix it up. Arena against infected; arena against humans; arena against infected and so forth. Music swells and you start another arena fight; music dies down and you know you cleared it.
The game's format gets negatively predictable and it mostly never catches the player off-guard or surprises him with the next gameplay segment.
Even looking at the dry numbers of X new enemies/weapons over the first, TLOU2 barely scratches 'expansion pack from the 90's' level. They nixed boomers and stalkers are astonishingly underused.
TLOU2 lacks one or two marquee gameplay features/innovations that i expect from 'genre-defining' release 7 years (or how long it was) in the making. That was the underlining sensation i had all through out the game, which stands above all.
When i recall my time with TLOU2, the first and foremost thought about it that i have is: 'is this really all what the game is trying to do in the gameplay department?'.
You get to Seattle Day 1 and have that wide and open segment on the horse and map and you go 'cool'. I think to myself maybe there are going to be several segments like this throughout and that's going to be TLOU2 gameplay's claim to fame.
Some time later you first get the boat and i start having this anticipation and expectation: 'OMG, are they going to have me roam a large city area, half-submerged, akin to the horse-and-map segment from before? Holy shit!'. Let's go, let's see what they worked on all this time.
A 10-minute mostly-linear ride later, that's the last time you even get to use a boat. Not even in a later segment where you approach an island.
After that short boat segment it hits you. That Seattle Day 1 segment was a one-off. There is no grand gameplay feature to set the sequel apart. There isn't much desire from the developers to innovate or push the formula forwards.
The ambition ends with 'just' a more competent, accomplished and fulfilled TLOU1 framework. And that's when my disillusionment with the game took hold and never let go.
Afterwards it was easy to see how the puzzle elements worsened compared to the first game instead of getting more prominent and involved.
The safe-cracking element in the game is frankly a laughable design decision. You are supposed to take the risk of exploring to find the combination but ND decided to negate all that by letting you 'brute-force' the safe.
All you had to was cycle through and wait for the distinct audio cue. It was easy to do even with regular TV speakers, so i did. Many times finding the combo after i already opened the safe by 'brute-forcing'.
I don't know how this ended in the game like that. I can only imagine they wanted to indulge the more 'casual' players, and in doing so completely undermined the point of the safes.
Then you have the numerous upgrade trees that, unlike in the first game, eliminate player's choice. You have to unlock everything in a set order and thus the game squanders the opportunity to offer varied 'builds' that would have given more distinct play-styles between players and more replay-ability.
And because of the numerous trees and abilities, some end up being boring X% better and some that you don't want to get but forced to in order to get whatever next.
I think TLOU screams for a limb dismemberment system for both infected and humans and it's a shame it doesn't have one.
