Pokemon? Well it was a big thing in my life when I was a midget. Watching the show every morning before school, buying the comic books, collecting/trading cards and failing school because the games were so addicting. Yeah Pokemon deserves some love, even though if it started these days I would probably look at it like it was some new stupid fad like Twilight. I'm not sure actually, the games were pretty fun.
1) Zapdos or Blastoise, there not only powerful, they also look mean.
2) I think 10: Red, Blue, Yellow, Silver, Gold, Pokemon Snap, Ruby, Saphire, Pearl and the a big collection of cards (You didn't say it had to be an electronic game). Also have the Pikachu tamagochi thing as well if you can call that a game.
3) Oh jeez, about 600 I think.
4) Nope! I stopped last year with Pearl, the game was no different from the originals and I got bored with it straight away. Maybe I'll go back and play the originals one day, just to see if nostalgia kicks in.
5) If I include all the games I think I got up to 400, somewhere around there. I did get them all in Red and Silver.
