None of the hundreds of gamers playing Starcraft II look in any way confused by it. Sure, this is a roomful of Blizzard fans - half of these guys have grown up with Starcraft. Nevertheless, to see not a single furrowed brow as a vast number of folk play a new game for the first time is an extraordinary thing. 'Starcraft' has become a by-word for 'hardcore', but what we keep forgetting is that, for all the pro-gaming trappings, this is a Blizzard game. Accessibility is all - anyone can play Starcraft II.
