Both games are awesome, but I think that in the end, I liked TLA better. I just wish I was able to carry my data over, but the code didn't work.

I loved the use of psynergy in the field; it made the puzzles more challenging. I hope the third game (if made) doesn't go to the Wii, partly because I don't have one and partly because Psy Power is abbreviated PP (PP+Wii= bad jokes). Hopefully it would come out on the DS (as Zeromus_X mentioned, the stylus would work very well with the gameplay).
