Here's an old topic that should be revived here on the new boards...

Which arcade game would you have liked to see on a home version, but never saw the light of day? Mine would have to be Zoo Keeper, Colecovision. Hell, I'd bet the Atari 2600 could have had a decent version of the game as well. Probably faster gameplay with sacrificed graphics-a common occurrence between the two. So, what's yours?
