TRIZ + PRIZM

I have experienced both TRIZ and PRIZM, http://www.theprizmgame.co.uk and have found PRIZM to be a method of fast flowing ideas and simple contradiction forming to problem solving,
In a single game of a few hours you can look over a complete problem technical product and processes,
I wondered who of you have used TRIZ and what your thoughts are as well as who has used PRIZM and your thoughts.
