This game has plenty of exploration opportunities for players willing to work through the game, especially the rafting element, which takes you full circle to your original base location. Some discoveries, like Claire's ability to crawl through small spaces in the jungle, could've yielded more benefits for the player.
Some climbing expeditions would be great for the next installment. A solid title for all ages that like a little challenge and fun multiplayer mini-games on the side. After you conquer the game and watch the ending credits you can play again as any of the four characters. A possible Wii release might expand the series even further.
