Every morning, or afternoon, I jump on and play Kingdom of Loathing 
http://www.kingdomofloathing.com/sta...p?id=whatiskol you only get a set number of turns a day, so it doesn't become an obsession.  I used to play Diablo II, and I was looking forward to Diablo III, but I don't think I'm going to let myself get sucked into that.  I may try Linux, again, and I'll work on getting SE4 to run under Wine.  Outside of that, I tend to hit up Jayisgames 
http://jayisgames.com/  to see what short Flash game I can amuse myself with for a short time.
