The prophecy foretold is now fulfilled: The Steam Summer Sale is live! That means cards to collect, a badge to earn, and yes, some deals on games. 

We'll toss in some links to deals we find particularly alluring (once the usual overwhelming server-crush has subsided), but for now you can try your luck getting in, and hopefully find a solid sale on something on your wishlist, at store.steampowered.com.
