Wow.. O.O I think I'm going to master Olimar first..his play style is just awesome. Very complex and strategic. Different properties per pikmin..
I could see certain types of pikmin doing more or less damage depending upon the character you face.
example: So let's say you're fighting Pokemon trainer, and he's using ivysaur. You would most likely want a red tiles stage so you get more red pikmin (I'm just guessing that may be how the pikmin selection works)..since they are imbued with fire properties they would do extra damage against Ivysuar, thus giving you an advantage.
See? The strategic possibilities involving him are more complex than any other character to date.
Sakurai you are a genius good sir.
