I only saw the PMD1 TV special thing. My dad came home one day and brought home Blue and Red rescue team. He said Blue was for my sis, and Red was for me, and I cried. I was a baby then and I liked the color Blue better than Red so I was sad. Eventually, I just played Red after my parents convinced me that they were pretty much the same game. But after that, I had to buy all my games. XD
I never tried 100 floor dungeons because I would get to the 56th floor and then I would lose!! But the bad part was, if you complete it, you would a Celebi would join your team!
And, yes there are 100 floor dungeons, mostly the Zero Isles( West, East, South, North).
Yes, I agree. Have you seen the mystery dungeon for Wii ( can't remember name)? It has more 3-D graphics. I know there is going to be a PMD3 with B/W pokemon, but I hope they include better graphics.
