Oldie Old Games

Neat, via joystiq.com, this little quiz on old video games was pretty fun. I got 24 out of 40, with a couple retries and some lucky guesses. See if you can get more! Update: make that 25 out of 40! It took me this long to remember "Half-life," number 8. Also, I am sure number 38 is some variety of "Bomberman" but I can't get it to work right...
