Turtles In Time for the Super NES... greatest darn game ever made.
The Turtles also are huge Muppet fans too, I know the creature shop made the turtle costumes, but I thought it was top class at the end of TMNT II, The Secret of the Ooze that they dedicated the movie to Jim.
Eastman and Laird's original comic is nice and as far as comics go, sci-fi as it should be done, but I thought the old school animation made it more appealing, the comic was violent as all ****!
Oh, and one other old school TMNT thing that ruled? Corey Feldman did Donnie's voice in the first movie... that rocks.
