When I play There Came An Echo, I feel like an idiot. I'm sitting in a room, alone, and talking to my PC. "Miranda, move to alpha three," I say to my squad member in a snippy tone one would use to tell a dog to 'drop it'--in fact, it's the same tone I use to frustratingly say "Xbox, on" before just reaching for its power button. Sometimes, my PC listens, and Miranda chirps an affirmative confirmation before moving into position. At other times, nothing happens, and I have to wait a moment before trying the vocal command again--this time, slightly louder; this time, it's more of a demand. "Miranda. Move. To. Alpha. Three."
