Jasonofthenorth: Thanks, rtcvb! I, too, loved Joust. No Atari anymore though knowing my 4 year old, the vultures would likely scare him a bit haha. Similarly, Ultima is probably too much for them currently. I'm a huge RPG person so it's killing me I have to wait a few more years before they we can play these together.
4... yeah just a little young... When he reaches 7-10 you can probably introduce him to the older computer games. Honestly i couldn't hardly read when i started playing Questron. You just press all the buttons to figure out what each does what, and then just walk around and explore.
On the other hand, if you got an authentic Atari controller, those things are pretty tough. Other Atari games to consider (
probably via emulator) would be Spy Hunter, Jump Man, Realm of Impossibility, Superman, Spy vs Spy, Astroids, Qbert, Defender, Missile Defense, Pole Position, My First Alphabet, Clowns, etc.
My mom said as a kid (
4-6?) she just set me in front of the computer and i would watch it for hours, so maybe just the demos running, or maybe the demo scene where they push the hardware to the limits. Hmmm with that in mind you could probably get one of those Rasberry Pi Zero's and put the atari emulator and stuff on it, then if he breaks it you only lose $5 in hardware :P (
Plus the joystick... and/or keyboard)
