According to Wil Wheaton of Star Trek (and blogging) fame, it is like the 40th anniversary of video games! He's got a great write up on it at
http://wilwheaton.typepad.com/What I really loved is his description of making your own games from a magazine...which I did in like 1979. Here is EXACTLY how it worked out, every time:
* Download a Commodore emulator, and track down a copy of COMPUTE!'s Gazette. Build your own game by copying the code from the magazine and compiling it yourself. When you're done, spend the rest of the day PEEKing and POKEing at the code to find the one character you transcribed incorrectly, and locate it just before you have to get off the computer for dinner. To complete the experience, have your mom come over and turn the machine off without writing your program to the cassette drive.
Thanks Wil!
