PokePark is in danger again, and it is up to Pikachu and his friends to save the day (no pesky humans, such as Ash, allowed).
While appearing quite similar to the first game, there are some major changes. First, there are two adventures (I assume there is no third). The first took my daughter (age 11) about eight hours to complete, but after the credits roll, the story continues (if one wants). The continuation seems to cater to the nature of a completist; younger players may be satisfied with the main, initial quest and forego the backtracking and gathering the epilogue requires (my daughter has not finished the second part).
In addition, this game is structured differently than the first. There is more need to battle, chase, and complete quizzes than participate in attractions/mini-games. Also there is limited side-scrolling action, and I will say that the game is a tad more difficult than the first. Not every character is a pushover, and players are required to level up the four Pokemon they use (and the leveling up process too is a bit more sophisticated).
Most of the Pokemon here are from the recent Black and White series, though many classic Pokemon show up. The game seems to be a worthy follow up with fine graphics and some interesting gameplay advances and tweaks to the old format. Remember that there is plenty of text to read in this game so very young players may need assistance.
UPDATE : My daughter completed the second adventure. It only takes a few additional hours of collecting items with the occasional battle. One can continue if one wishes to collect all the remaining Pokemon as friends. Plus, the Battle area offers some additional tough challenges.
