I love these games, but could you download for people who want to play the games for free?
This is a service offered by the WildTangent. They offer downloadable games for a price and the possibility to play some free games on their website. Access the Free section to play them. Of course, you have the possibility to play free games as well, but they will be in demo mode until you buy them.
