The License for pygame:

This library is distributed under GNU LGPL version 2.1, which can
     be found in the file "doc/LGPL". I reserve the right to place
     future versions of this library under a different license.

     This basically means you can use pygame in any project you want,
     but if you make any changes or additions to pygame itself, those
     must be released with a compatible license. (preferably submitted
     back to the pygame project). Closed source and commercial games are
     fine.

     The programs in the "examples" subdirectory are in the public
     domain.
