First off, note to everyone who doesn’t already know but I LOVE Shadow of the Colossus. It is one of the best games ever made. There, I said it.
The Last Guardian is made by the same company, with an aim to focus on the relationship between man and beast, similar to Agro and the Boy in SotC. The thing about this game is that you know one of the two has to die at the end. And that makes me sad.
