I'll try to get this link added to my own website soon, but I changed computers quite awhile ago and my IT guy (i.e. my husband) hasn't loaded the website editing software yet. LOL! 

Anyway, I'm not sure who shared this website with me, but it has a lot of really exciting links to educational games.  These are very sophisticated, interactive games designed primarily for non-profit organizations such as museums and schools.
