There are tons of free historical games, interactives and simulations on the web. Playing history aggregates info on these resources in a simple, searchable database making it easy to find, rate, and review historical games. The site currently has 126 shared games.
Reflections: As my first experience with developing a significant web project it was a challenging undertaking. I learned how to design web resources for different audiences, how to create page mock-ups in Illustrator and Photoshop, how to translate those mockups into HTML and CSS, and how to use Omeka as a content publishing system. As evidence of my success, the PlayingHistory has been used by more than 20,000 teachers since I launched it nearly two years ago.
