One of the best value Pro models out there next to Dead Pool. The pro offers great features without feeling like it is missing out on some of the toys from the Premium/LE models. It's also great to look at. There is so much going on in the artwork and playfield layout with ramps, toys and wire forms that it feels like it is worth every penny when compared to some other more recent Sterns like Led Zeppelin.
For a title based on a children's cartoon, it can be a tough game. When your aim is on, the flow is great, and chaining ramp shots feels really gratifying. When hit perfectly, the Krang combo, 1-2-3 foot combo, or chaining left ramp to right ramp to ninja pizza to start a mode is lightning fast and feels amazing. That being said, if your aim is off, shots like the lair, ninja pizza, and the tight right orbit can feel clunky and add to frustration. Not that you need more frustration, since the gaping left outlane provides more than enough frustration for most players. The spinning pizza disc adds chaos to the playfield and forces the player to stay on their toes as it imparts spin or throws the ball towards outlanes and drains. If the game has too much pitch, some shots can no longer be backhanded (left ramp). The right ramp seems to always be accessible by backhand, and feels good doing so.
Since the 1.41 code update adding final battle and half shell challenges accessible from the start, and some tuning, it has really helped the game. Half shell is a blast, and is great to start up for the younger or more beginning players as it will keep relaunching the ball until they make the shots giving a more forgiving experience. The Co-op feature is also great to get younger players into the game, or just to have fun with friends with the ability to have 1v3, 1v2 and 2v2 battles.
Some tuning still needs to be done. Multiball modes have some blinding lighting effects that make you lose sight of the ball, which seems a bit unfair. The 1-2-3 Foot combo needs to be reworked since it seems to constantly trigger, and has what feels like a meager payout for the effort. Scoring in general is low, and some of the Turtles could use some rebalancing as Raphael is really the only character to choose if you are chasing a high score. Donatello is almost handicapped since it all but forces you into turtle power multiball before you can start a mode and really build up your score. The lair ball save timer is a must to set, and really should be the default. Stern should also add a launch ball save timer option as it can be frustrating to lock a ball, and then the launch sends it for a center drain.
All in all, it's a hugely addicting game that challenges the player with a lot if fun shots to explore. While it can be frustrating at times when not on your game, I find myself coming back to it again and again.
*Edit* I updated my ratings after I owned it for a year or so. Scores dropped on lastability (I played it a lot but ultimately let it go), lighting (those flashers blind you), and layout (there are some clunky shots that required too often)
