For those who are interested in using freeware programs, here is a url to the pricelessware site. These folks collect and review lots of freeware applications, then keep only what they consider the best on their site.
Their site does not include games as a catagory, but they do furnish links to other sites that do include games.
Here's the link: http://www.pricelessware.org
It's worth a visit, and I hope it wil be useful for you!
