Not an original, but a good game in it's own right.
In the field, you can actually see the Pokemon around you, and decide to approach or avoid them. I recommend catching Pokemon you think would be most helpful in your current location. Capturing the pokemon is fun. The Pokemon will move about on the lower screen, and you have to quickly use the stylus to draw circles around them. The bad part of this is if the Pokemon touches the line, it will break. Or worse, when the Pokemon attacks the line, you lose energy. When you run out of energy in the styler, it's game over.
While it is based on Pokemon, I think anyone could enjoy the game play and find it interesting.
The graphics are actually pretty decent based on the other Pokemon games.
The sound is ordinary, nothing I'd recommend.
In conclusion, if you like pokemon, try this game. If you don't, try it anyway. It's game play is unique to the series, and unique to the system.
