I think if my 5 year old son were able to read, he would have loved this game. But, he only knows how to read very basic sentences, and the beginning of this game has constant subtitles you have to read where the characters are talking with each other, instructions for the game, building the storyline, etc. Older kids would probably really enjoy it. We both were bored with it very quickly.
Pokepark wii wonders beyond is in a word delightful. It is a huge improvement on the first pokepark game, in which making friends is a lot simpler and a lot less entertaining. I say this because unlike the first game this game has an expansive world to explore. It may not be as in-depth as the usual pokemon games, but none the less it is just as fun. With battles ranging from easy to difficult, some well designed minigames, and a world full of exploration you will find an entire days worth of play time and fun.
