Most notable among today's "Daily Deals" is Super Meat Boy for $3.75, a price so good you should consider it now even if you're waiting for the Mac version (thanks to Steam Play, when you buy the PC version, you'll get the Mac one when it's released); Battlefield: Bad Company 2 for just $6.79 -- just in time for the Vietnam expansion; and the Oddworld Oddboxx for $12.49. There's also a one-day "Holiday Bonus" each day of the sale, which run until January 2, contingent upon ownership of another game. Today, you get an extra 10 percent off Portal if you have Half-Life 2 in your Steam Library.
Steam is also offering crazy discounts on publisher packs -- like every Valve game for $50 and every Square Enix/Eidos game on the service, including Batman: Arkham Asylum, Lara Croft and the Guardian of Light, Just Causes 1 and 2, and Front Mission Evolved, for $74.99. These publisher packs will be on sale through January 2.
