Remember a couple entries back, when I was talking about how awesome the second and third Ninja Turtles games were for the NES? Well, imagine that excellent, but riding a cool skateboard and eating pizza, because like, that's how totally awesome the fourth Turtles game for the SNES is.
Quite frankly, it's one of the best games for the system, which is amazing since it came out in 1992. Although technically titled Teenage Mutant Ninja Turtles IV: Turtles in Time, my friends and I just called it Super Turtles. You see, this was a clever double meaning, in that it was the first Turtles game for the SUPER Nintendo, and because the quality was quite SUPER as well. Ha ha ha, aren't I so clever? (Yeah, I'm totally taking credit for it right now.)
Anyway. Besides some obvious technical enhancements, Super Turtles is vastly superior from a planning and layout perspective. Stages feature more thing to interact with, such as manholes, damage-causing traffic cones and exploding gas tanks. While regular enemies are still numerous, bosses feature a life bar, which makes it much more convenient to fight them; you know if you have enough life to fight conservatively or aggressively.
The four turtles each have different weapons and attacks, and slight differences in attack power. You can also now run and use shoulder tackles, and there are combo attacks allowing for throws (more points) and back-and-forth slams (splash damage on nearby enemies). This is in addition to the usual weapon attacks, a jump kick, a slow but strong jumping weapon attack, and a character-specific special attack.
Touching on the technical enhancements – This is by far the best version at capturing the spirit of the animated cartoon Teenage Mutant Ninja Turtles, which is what most kids I knew liked about it. The music and sound effects are also spot-on, and heck, they even managed to cram in almost all of the relevant characters from the show. The time travel aspect of the storyline means there are some silly cutscenes that totally fit in with the flavor of the show.
They attempted a 3D remake for X-Box Live or Network, whatever it is called. Although I haven't played it, I've heard it's ass, so stick with the original. It ranges for $2 to $30 on eBay, depending on whether you want the box and manual. I wholeheartedly recommend it!
