1up's Essential 50 Videogames.

From 1up's Essential 50 Videogames. Italicize the ones you've played, bold the ones you've beaten (or played to such a sufficiently high level that you could routinely beat the scores of your average joe). Make a note if you didn't actually play it on its original platform, but instead played it on a MAME emulator or some "Greatest Hits" package.
