Educational School Games

I'm looking for content for many subjects and not just specificly for a domain.

Certainly the project to Kindersite http://www.kindersite.org They have carefully selected the best games available on the net. I copy / paste from their site:
"The educational games Kindersite 7 to 12 years, is used by 18,000 schools in 157 countries. Recommended by teachers worldwide as the best way to introduce games in education."

starfall.com has many different kinds of games for pre k - grade 5 that affect many different subjects

I agree with Joe, the Kindersite is an excellent free resource. The value they have is they only add great content to multiple subjects.

Meteora is a good site but it is specifically to learn English as a first or second, regretted that the question for all subjects.
