I'm just about done on a second play through. The level of details and cross-references to the two main timelines is really good. Definitely worth going again IMO
I started a second play though on Hard+ with my first game load-out and infinite ammo and unbreakable melee weapons, my reasoning being I could concentrate on enjoying the story and combat without rationing arrows and hammers too much, plus I could play a more satisfying stealth game
Found TLOU2 as satisfying as it was affecting, gameplay wasn't the best thing ever, but everything was driven by a great story. A real masterpiece.
Now onto Tsushima to slash my way through the rest of this generation.
