I know I'm late to the party but just completed this, a bit of back story;
I had the first game on the PS3 from launch but it came at a time where I was falling out of interest with gaming so never really played it (my OCD had made gaming difficult so if I didn't do something perfect I'd replay the section over and over again until I got it right and obviously replaying the same bit over and over again became boring so yeah I stopped gaming). Despite this my wife got me a PS4 and I got the remastered edition on that as well but again never really played it until last year...
PS5 hype got to me around that consoles launch so I started playing through all my old PS4 games including TLOU so I've been in the lucky position of being able to play both games back to back (bar a quick break to play through Mile Morales) and have absolutely loved both. Honestly I can't separate them, both absolute masterpieces and because I've played both back to back I'm absolutely gutted I don't have a third to start playing straight away

Really hope Naught Dog do do a third (though at their current pace it'll probably be towards the end of the PS5's life cycle

)
