I'm late to this topic, but since I run a TLG group, I decided why not.
This game took actually 9 years to develop and came out 2016 (began development in 2007), and the fact it's not known more today/talked about is honestly insane.
The Last Guardian is a game you could binge-watch, and probably not get tired of. I have personally re-watched the series 4-7 times, and if you couldn't tell, loved it so much more each time.
The bond between 'Trico' and the Boy is honestly so well done, and it set my priorities extremely high for other games with the same sort of plot/story.
Sadly, due to the long development of the game, I hardly doubt another one, a movie, or a book will be made on it, which is why I created my RP Group to sort of 'reignite' the love for the game. The Last Guardian really deserved a lot more love than it had, in my opinion. And if you're not one for a slow-pased, emotional, puzzle-game, I still think this game is for anyone who wan'ts to enjoy the visuals, the bond, and more.
