I have mentioned my fondness for Peggle before (buy it for your mother, unless she is the Halo 3 sort). With a hat tip to Cuppycake for the link, The Escapist has a stellar review of it. 1:50 to 2:03 summarizes everything well. (Yes, four links in one paragraph; click the LAST ONE. Okay, that was five, but the last two were the same.)

Peggle is one of the rare few “free” games that I have actually paid for the full version. Everyone in my family enjoys playing it. It infected people at work too. Great game.
