How can I block game player spam (ex: Mafia Wars) on Facebook without deleting friends? - sorority life how to delete posts

I have friends in Facebook, the ever Sorority Life, Mafia Wars, Farmville, Farkle, Jungle Jewelry, etc. .. are Facebook. I do not want to block because they are my friends and I want to read updates on their status, but I'm reading about the game online tired! Is it possible to block these messages?
