I started playing the last of us 2 remastered. I didn't play the original (but did play 1 remastered). I don't know if it was modified "for modern audiences", but it would depend a lot.
Having more characters from Asian or African descent would please me. Making it look more like the (in my opinion) excellent tv series would be less great, but understandable. Removing the whole "military is bad" arc (like they did in the tv show), would suck.
Got released in 2020, but Wikipedia said development started in 2014. PS5 version is called remastered, no idea how much is different.
