Avoiding the obvious--
#2 Donkey Kong Jr. for Colecovision (Donkey Kong, of course, is #1)
I could make a small fort with the amount I have. Any homebrewer's out there who need some shells???
#1 Auto Racing for Intellivision (I've actually seen more of this than the packed in Las Vegas Poker. Did people trash these?)
I am so sick of Auto Racing for the Intellivision!
And following the rules given...
#4 Fishing Derby for Atari 2600 (Pac-Man #1, 'Stroids #2, Combat #3)
Stating the obvious...
Parsec (TI-99)
KC Munchkin (Odyssey2)
Sorry, one last thing. You ever notice how often you run into a packaged game (Star Raiders [2600], Turbo [Colecovision], etc) solo? It's like the game survived, but not the accessory. It's like, what am I supposed to do with this?
