Ok, I just read this in my December 2010 issue of Mac|Life.
Adandonware
Classic games no longer in development can still live on in emulation on your fancy newfangled Mac. Start with Macintosh Garden (macintoshgarden.org) which keeps a meticulous archive of "abandonware" that is now free to use. you'll need an emulator but you'll find lots of help and advice here too. Relive the glory days of Marathon, Monkey Island and more!
