Ian's attempted a Zool remake before, back in 2004/05 (when he was still Zoo Digital Publishing) they worked with DDI (Data Design Interactive) on a 3D Gamecube/PS2 version of the franchise. The game sucked bad, and got canned (luckily). DDI changed the lead character in the game from Zool to a gingerbread man, and released the notoriously bad Ninjabread Man (http://en.wikipedia.org/wiki/Ninjabread_Man
). I think legals followed.
I still have the animated intro video to this Zool remake. Will upload to youtube when I get time.
It's a shame they chose to work with those guys, at the time lots of fans were sending in ideas and concept artwork that was so much better.
