That battle.net launcher we’ve heard so much about, the one that makes it possible to log in to all your Bnet games at once and then not do it again for a month, has entered open beta today. What that means is that it works but they aren’t going to force it on everyone just yet. But if you do want it right now, you can get it here.
Basically it works like any other Battle.net launcher you’ve ever used, except that one you install it you don’t need the other ones. It’s Steam, essentially, for Blizzard games; it puts your stuff all in one place and keeps them updated. No store here yet, but surely it will come. There is a cool news section, though.
