I found a nice loose copy of Worm Whomper - one of the games that made me want an Intellivision. I was hoping to have a CIB copy (love the box-art) but I'd rather have the game than not. I can complete my copy sometime in the future.
Played this at a friends house not too long ago. It's a surprisingly tight and very fun game. i'm shocked it wasn't released on the Atari 2600, seems like it might have been doable.
