To be honest, it was a mismatch of expectations we have based on prior knowledge of a medium, and what the game had actually to offer. Just like you know that after being 45 min into a movie you're reasonably not even close to its ending, it didn't even cross my mind that what I was seeing was the game finale.

I sat down there, looking at the screen like a fool, not understanding that the game had ended. I won't deny it, I wanted to bring Lester back home, through many more adventures! :)
