Oh so many games, and free.

Go visit 1UP.com Great site for all game players or go directly to this link 101 FREE GAMES for awesome free games. There are multiple pages of incredible fun games. NOTE: there are a couple not for kids games listed here.
BTW if your at work now just tell the boss you gotta go home because your feeling sick with one of those 48hr flu things, because your gonna be busy playing free games for at least 2 days. HaHa!
