Pros: Nice visuals at 480p. Very easy to pickup and very easy linear game-play: children friendly. Easy menu interface and in-game tutorials. Respawn at the same location when you die. Other mini-games.
Cons: Some Wii tilting levels will get you testy, but very doable after a few practice rounds. It didn't make much sense to me when the rest of the game is very simple yet it becomes moderately difficult during the Wii tilting game missions. It was extremely fast paced compared to the rest of the game (i.e. ice level, mine level). You may have to help your children pass these levels. It was just like Link's Extreme Snow Boarding in Twilight Princess. Other than that, it was starting to become repetitive.
Here is a game that makes a great example of its target market: children. Me and my younger brother completed the game in just a few hours.
Tip: 1). Use C often to center the camera.
2). It was becoming very tedious sneaking up on hunters to scare them. I found it much faster to simply run up to them and then growl. Sure, you're gonna get shot at, but with unlimited respawns who cares. However, there are 1 or 2 levels where you have no choice but to sneak up on the hunters.
Don't let the more abstract low ratings fool you-- the game isn't that bad. Controls are very standard. Slow? Hold down Z like they taught you and it won't go so slow anymore-- but they won't remind you later. Which brings me to the first and largest issue with the game: the adventure mode asks too much of younger kids, from difficulty level wildly swaying from really easy to "wow this is tough" and back.
And let's also be clear in this review that this is essentially two games: an adventure mode that doesn't take too long to beat (if it takes a day and a half, that's pretty good for a kids game); and a series of mini-games, unlocked primarily after you've beaten levels of the adventure game. The mini-games are good, more fun than the adventure game and can feature 4 players. They also skew much better for younger kids. My biggest complaint with the mini games is the fixed camera that is unusually far away.
This game is available pretty cheap from Gamestop and others ($20 or less)-- it's worth the rent and maybe even the pick up as a kids game for a household from ages 4-10 (ages 4-6 for the mini games).
