I still have my Atari and it still works. I only have one game for it though (Centipede), I think my dad threw the other ones away I had Mrs. Pac Man, Pole Position, Dig Dug, Keystone Capers, Food Fight.....
My favorite system is the original Nintendo though. Mario 3 is the best game ever. Mario 1 is also good. Mario 2 is bizarre, it should have been called "Mario has a bad trip" it is nothing like any of the other Mario games. I curse the day that I sold my Nintendo at a garage sale.
Sega Genesis is the most sophisticated system that i have. I it as well. Sonic!
