Serious Games

Is that an oxymoron? Apparently not, since there was a
Serious Games Summit in Washington DC.
Since I've been taking this class and playing around on SL and Lemonade Stand, to name just a few, I've also been blogging about my fascination with gaming as a leisure activity as compared with watching TV. Most of my peers do the latter. I found myself feeling a bit guilty for "playing," even in the context of a class. I blogged about it, pointing out the cognitive underload of TV to justify my choice and wished more "adults" would losen up and play online PacMan.
With so many serious games being created, I wonder if those less serious games won't be quite so snickered at.
