why have almost all of the pokemon from Red, Blue, Yellow, Silver, Gold, Crystal disappeared? Most of my favorite pokemon like Tyranitar or Dragonite are gone. This just messes up the whole game.
Because it's different! And finding different new Pokemon is fun! And it will make sure you don't always use the same, strong, boring Pokemon, but now you must use different ones! It's a new game! Wow!!!!!! Only Sentret is not in it anymore..
