Playing Halo, I suddenly remember some evenings of play, when I was a child. Running, evading, laughing and screaming aloud. Other parts in the game remind me from books, movies. Larry Niven and the Ringworld, of course, but so much more also. At certain point all that battle becomes purely mechanic, and then everything is just about reaching out. Getting to the next hilltop, over the brook. Playing for being, being for playing?
