Here are places I mentioned in my talk –

Sudoku Online (one of many, www.websudoku.com)

Puzzled Sheep (www.miniclip.com/puzzledsheep.htm) - turn down your volume first

Escapa! (the red box game, www.iol.ie/~dluby/escape.htm)

Live Long and Prosper (MIT, education.mit.edu/pda/igenetics.htm) - instructions only, not the game

The 2006 Horizon Report (www.nmc.org/horizon)

The Daedalus Project (research on MMOs, www.nickyee.com/daedalus/)

Essential Facts about Games & Youth Violence (ESA, www.theesa.com/facts/games_youth_violence.php)

Alien Games (www.aliengames.org)

Game Theory (www.gametheory.net)

World of Warcraft (www.worldofwarcraft.com)

Second Life (www.secondlife.com)

What might we be able to learn from the study of game playing and on-line games that we can apply to more traditional course design, even without explicitly introducing games?
