Pokemon Crystal is for Gameboy. And we will soon have pics for it. It was released in September in Japan. You can catch the same Pokemon in it like on Pokemon Gold and Silver. You can trade Pokemon over cellular phones too.
Its not such a BIG difference. its like Yellow compared to red and blue. The Pokemon Centers are the same. Exept for the phine part of course.I think when you go to the trading room, you get a choice. To trade over phone, or lik cable.
Heres the cover of Pokemon Crystal. As you can see,it has a pic of Espeon on it. It makes me think, if Espeon is on one, why not Umbreon. Maybe they're making Pokemon Daimond!?
Heres the intro screen on Pokemon Crystal. It has a shadow pic of Suicine, the water Legendary dog. Pokemon Crystal has a lot more better graphics then any other gameboy game!
You may also choose between a girl or a boy. Which is a big releif for all the girls that like Pokemon out there.
