Idle talk is kept to a minimum when you're playing Blizzard's latest in its place is a gentle mixture of half-formed strategic mumbling, sighs of defeat, and clicking, always clicking: clicking that's probably a dozen or so fingers frantically directing waves of Firebats, but could pass rather well for the juddering claws or antennae of some kind of horrible oversized bug.
Close your eyes in a room full of StarCraft II players and you could be forgiven for thinking you were in the presence of a giant space cockroach, or a vast interstellar weevil, or something else with nasty chattering mandibles.
