Anyway, my votes for best games on the 7800 (my fav Atari machine, still)
Joust - 2 player or solitary, man this game is a BLAST! One of THE best and most playable ports ever (Lynx version is darn good, too)
Dig Dug - A very faithful translation and frustrating into the later levels (but very fun, still). Will always hold this game dear
Galaga - Love the bonus music upon getting all 40 bugs. Listen to that magnificently produced pseudo stereo surround sound! (I might be going overboard, but I really love this game)
Ace of Aces - A tough game, but I remember playing this non-stop for hours when I first got my 7800 (and laughed at all the NES owners with their excessively ugly, boxy clunker)
Food Fight - Never played this game til I bought it for this system. Now, I can't seem to stop.... Addictive and fun!
