As a newbie (few months), I find a lot of fun with TMNT. It is challenging, though. The speed of the game and trying to make shots on the fly make me realize that the years are past when I was really good on Call of Duty (i.e., reaction speed is not there like it used to be), and sometimes it makes me sad. Being a newbie, I'm glad the MBs are 'easy' to obtain, but I agree without the MBs, scoring stays low with episodes. 123 foot seems to happen way too much and I don't notice it having a good score payoff. The left outlane has twice as many drains as the right. And if I don't sink a shot, high chance it will drain stdm.
I like the theme, and so do my kids. The co-op modes, and the variety of modes, is a welcomed addition for our family (we have 4 kids).
I plan on increasing the ball plays per game, and probably narrow up the left outlane entrance. I have way more games on DP, and find myself enjoying shooting it more due to less frustration (DP games are longer, TMNT games are shorter, sometimes embarrassingly so).
Just a newbie comment to see how it compares to the vets.
