While surfing around seemingly at random, I ran into this site:
This site essentially provides a live-type disc loaded with Linux and games that work with Linux, all for free and for our enjoyment. Although I already have Linux installed and as such am unlikely to just download and try this when I can just download and install the games directly, the website does have a nice list of Linux compatible games.
So, if you’re at all into Linux and want to have some fun on the side, by all means, check out this site.
