I am a regular follower of Aaron William's webcomics and blog. http://nodwick.humor.gamespy.com/ At his blog he usually throws in a recommendation for a flash game or two, they are usually well worth checking out. In his latest entry (29th December 2009) he mentions this combination of Super Mario and Tetris which I found quite funny for the couple of minutes the surprise at the concept takes to wear off. It is a good laugh for those who lived the 8/16-bit console era: http://www.freewebarcade.com/game/tuper-tario-tros/ Feel free to comment or add to this thread your recommendations of casual flash games in any genre. After all, we all have too much time to waste during the no-pro-tennis seasons, don't we?
