This is a true classic.
The graphics are awsome, there's not much to say about them, they just look cool, and I hate to say this but "cute" too. The battles are fun and unique, they are also not randomly activated, you see them running about the wilderness. They will have a green smiley face above there head, and if you're weaker than them Their face will trun red and they'll chase you. If there face turns blue and sad, they'll run away, this happens when you are stronger and more likely to win the fight. It adds a bit more variety and it's refreshing. There are no voices;however, there are some catchy little tunes and sounds.
