All your Blizzard games in one place!  Once you log in through the new Battle.net desktop app, you have access to all your Blizzard games. Get in a quick World of Warcraft dungeon run with your guild, play a few league games in StarCraft II, and then head over to Diablo III and level up your barbarian without having to sign in separately each time. You can even have your computer remember you for up to 30 days for even easier access.
