Think CP is an interesting game, I still like it... but it does get old pretty fast, since its relatively easy to get to the cash fights.
then it's like your doing the same thing.
build health
beat cash fight

Multiballs are always fun, but they aren't really worth anything.
the training items are cool if you use them strategically.
Then again it's pretty much the same thing for most games eventually. CP just gets to that point a little faster then others.
CP is a good beginner game, or for someone who isn't a hardcore pinhead.
