Konami actually changed up Turtles in Time enough from the arcade to SNES version to actually make the game worth playing twice. The best addition to the SNES version was that they actually implamented the "Throwing Foot Soldiers into the screen" into a boss battle.
Word. My brothers and I would play TMNT: Turtles in Time whenever we wanted to while away the hours (though with all 3 of us playing together, we'd usually beat the game in about an hour).
