perfect game
very good for mega man forever

A great addition to the Rockman EXE series.
Battlechip GP is a different type of EXE game that contains all of the fun of the main series. You choose a character and a corresponding Navi, and each of the six playable characters has their own unique motivations and storylines. There is tons of replay value in creating your own custom chip decks to use in battle, and the multiplayer aspect is great also. Prepare to spend LOTS of hours customing your navi and fighting many challenging opponents in the tournament. One of the great Rockman GBA titles.

Nice past-time
Slow-paced, a bit repetitive, if you're looking for great plot-twists, area-explorations and other such things, but still a nice, nice way to pass your time.
The Battlechip GP tournament is what the title foreshadows: a tournament. A series of challenges, going from easy to more difficult as your rank increases. The Navi of your choice (Rockman, Blues, Roll, Ring or Turboman) fights the battle on his/her own, requiring you, the operator, to help only when strictly necessary. The gamer's main efforts will go in planning the winning strategy, collecting all the chips (and there are many), and unlocking the "secret", post-game tournaments.
The simple game-mechanics aren't a bad point; actually, they make it so that this game can be played even from those who don't know Japanese - in the end, I think Rickman EXE Battelchip GP is definitely worth a try.
