Summary: Like many of the other posters have said, there are bugs in the 2 player mode with player control and screen tracking. The game itself is fun. One major gripe is the inability to truly save where you are at on a profile. Example, saving while in the Forest puts you back at the beginning of the forest level rather than 3/4 of the way through when you go back to play it.
Summary: Rented this game for my 5yr old, who was too frustrated with the previous Ben 10 games-- he loves this one! Occasionally he gets to a level that is too hard for him, so we enter a cheat code to skip to the next level("portal"), and the fun continues. I will likely purchase this game.
Play side-by-side with your kid (early teamwork development)

Summary: This game is exactly like the previous Ben 10 game. The gameplay is shallow and the controls aren't top notch. BUT, this game lets you play co-op with your kid. That alone is worth the price. This game isn't horrible, especially if you have a Ben 10 fan in you house, but it isn't one of the better action games on the Wii. There is a reason why this game is always on sale. My son and I have a blast switching up the characters.
Summary: Ben Tennyson's back and badder than ever in his new series "Ben 10 Alien Force". Now you can live out his adventures in the new "Ben 10 Alien Force" video game ! Join Ben, Gwen, and Kevin as they head out to new places - though some are familiar to the series' first season - and take down some new foes in vast 3-D areas with many levels and stunning (though mostly dark) graphics.
Summary: My six year old boy and eight year old girl love this game. It took them a while to get used to it but now they just dig right in and fight the aliens until their gone and go on to the next level. The grunts and grones are kind of violent sounding and I would rather see them playing nicer games but this is not blood and gore.
