If anyone played a bunch of the Space Quest / Kings Quest type games as kids, you may be as excited as I was to learn that there is an emulator type program called SCUMMVM out there that can play all of those games in almost any environment.

I just downloaded it for my Droid and its really fantastic to be playing the Kings Quest series again while sitting on the metro every day.

Check out MAME as well. Link here (http://en.wikipedia.org/wiki/MAME). Similar concept, but also useful for those interested in building an arcade cabinet of their own.
