They're listing sales for Cake Mania, Cooking Mama, The New York Times Crosswords, and Konami Classics for $9.99 each. I've played all four. Konami Classics and NYT Crosswords are great deals and well worth the money if you like old arcade games and crosswords, respectively. Cooking Mama is okay - $10's about the right price for it. And I don't really care about Cake Mania, but my girlfriend won't leave it alone, so your mileage may vary.
