Prince of Persia (I read a few weeks ago that the author just found the source code to this after thinking it was lost this whole time): Rad Warrior (I've been trying to find this game since I found emulators 10 years ago.): Here are games that I remember very strongly. Some Atari 400, Mac, C64, Amiga, Genesis and SNES. Oh my gosh, I can't believe I just spent the last few hours finding all of these games. I took a vacation from computers in the 90's and it shows. What I find absolutely amazing is that I knew very few of the 16-bit games that GregBug posted.
I don't think I've recovered from growing up.
