What's your favourite Pokemon Game?  The Friendship system in Pokemon Yellow I hear was pretty sweet.
My favorite game was Pokemon Ruby and Pokemon Sapphire. Have you played those?
I don't know if I can choose a favourite!  Is Pokemon Ruby the one where you can choose a Treecko as your starting Pokemon? 
He is one of the options, or you can go with Torchic or Mudkip. 
Which one of the three did you usually wind up choosing?
I usually go with Torchic because I like his evolutions later on. 
Makes sense to me!  Do you have a favourite pokemon?  Charizard is pretty popular I guess, though I heard it was originally called Lizardon in Japan.
Oh wow that is interesting to hear! My favorite pokemon is Pikachu. How about you?
Hard to say, there are so many good options to choose from aren't there?  I think you made a good choice with Pikachu though.  Some rare ones like Dreepy and Sinistea can be attention grabbers, but I don't know what I'd choose.
There are a lot of them, but you gotta catch em all.
