Hah, I know what you're thinking. You and your tiny little brain. You're thinking "gosh, Valve's going to sell Team Fortress 2, Episode 2, and Portal on Steam soon! I can even preorder it!" That's as far as your train of thought goes. That's the beginning and the end, the alpha and the omega.
I bring you news, dear reader, of Valve's other contribution to keeping you at your computer far beyond the point where you should have gone to bed. This contribution? Peggle Extreme.
Now with 80% more Extreme
Peggle Extreme comes (exclusively?) with the Orange Box Prepurchase which you can read all about in this thread's sister post. What's Peggle? Well, you ought to know, because it's basically what you'd get if you could snort Tetris like crack. It's that addictive basically. Why Peggle? Apparently it's so addictive that it has transformed much or even most of Valve into the Peggle equivalent of headcrab zombies.
Valve vs ASPCA: Round One. FIGHT!
Peggle Extreme is like, an Orange Box flavored Peggle. It's got 10 levels which is less than Peggle Deluxe or even Peggle: Sold My Body To Buy One More Play, but it comes free with your preorder so there's to be no complaining, got that? It's Peggle! Can't complain about Peggle. Think of it as the Bioshock of, uh, addicting games? Why not.
