I don't understand how is openclipart.org related to Microsoft EULA?
The images on openclipart.org are mostly licensed by PublicDomain.
sorry for my bad English. What i was trying to express was:
openclipart.org has a good license but not so many sprites (monsters,
sword fighters, aliens, battleships....) that i could use for a game.
Microsoft.gallery has a lot of content but as far as i understood the
license that i have to accept when using this content, it gives me far
less freedom than public domain.
