Kids often ask me "where did you get that game".  Often the answer is
"I bought it"... and then they ask.. "can you burn me a copy" and which point
I go into a oft rehearsed tirade about piracy and the need to be "above reproach".
  "Or", I say, "it's just a demo and you can download it too!".

There are many gaming download site but my personal favourite is from England.
 GamesDomain.com is great and
doesn't force you to register and give away your soul to get something another
company really wants you to have!   Check them out.
