Hope you dressed warmly, because HBO set up a "Winter Is Here" environment for "Game of Thrones" fans at San Diego Comic-Con. It's open to anyone with an SDCC badge, but be prepared for a line that stretches a few blocks.
Planning on going north to defend The Wall? Hope you played a lot of Fruit Ninja. The last activation arms you with a dragonglass dagger (it's actually a PlayStation Move Controller) to fend off waves of White Walkers.
