It's a lot of fun if you like running and blowing stuff up. Tons of stuff to do like building up your character or start to take on gang lords. I knew Crackdown was wroth the $60, even with out the Halo 3 Beta. Sooner or later this week I'm going to have to take on the 2 player Co-op to see what it's like.
I might get the TMNT because I loved it in the arcades and on the SNES. Now if either Wii or 360 can get Turtles in Time.
