Zatch Bell Electric Arena is about as fun as eating nails.
Graphics aren't terrible. You could probably buy it at a store for less than $6.00.
Only eight characters. Combat is complete button mashing. Minigames are boring wastes of time. Storyline makes no sense. The "item collection" is a joke.
Things to do besides play Zatch Bell Electric Arena:
Read a book, clean your room, watch TV, write a story, make a sandwich, eat the sandwich, play outside, draw a picture, whistle a tune, sing a song, go see a movie, go rent a movie, make a list, wash the dishes, order a pizza, play in traffic, adopt a highway, swim in a quarry, build something with Legos, build something with Megablocks, make a game review, pop bubble wrap, donate to charity, cook a fancy meal, throw away the meal you failed to perfect, listen to music, play any other game.
