Well that would probaly be later on in-game. Right now they just need to start with the basics playing the game, working on items, trading, ect. Probaly later on like megamane said. I think there should be pets you can buy from like a store with in-game currency. Lots of games have that stuff. They can give extra defense or extra attack level. This game is going to be awesome I can't wait to see what it will be like
