From a purely geek standpoint, Ankh was also a kickass game for the Apple II series. Although ostensibly an arcade game (move, shoot, avoid) it was actually also one of the first really mindbashing 'puzzle' games - shoot through this small hole, move the lever, open the other room, etc. etc. It took me about ten games to figure out that it wasn't just a slightly boring shooter; then it took me like four nights living on Frito-Lay to finish it. Ahhh, them days.
