Not that you'll see me trading in my DS anytime soon... The olden days of gaming on a Nintendo handheld produced some classic titles and some licensed crap. Luckily, you'll find that Avatar: The Last Airbender - The Burning Earth falls much closer to the former category. Classic it is not, but fun to play and solidly programmed it is. The graphics are pretty static across individual areas and there aren't a lot of places to explore, but the environments you play around in and the characters featured are nicely made. The characters especially will please fans of the show that are excited about a chance to control Aang, Iroh, Katara, Toph, and Zuko. Appa is thrown in for good measure, but not to the extent that it matters much to whether the game rules or blows.
There's no spoken dialogue, but cut-scenes are subtitled and there are segments between the major levels to explain the story. The sounds during battle and in the exploration of each level are central to gameplay. There are some visual cues when you power-up your abilities, but the distinctive sounds of each character's ability help to gauge the correct time to attack. Enemies also have similar cues as to their big attacks. The work done on design in all aspects of The Burning Earth is solid stuff. It's more than enough to please fans and almost enough to justify a purchase by anyone that likes a relatively challenging 2D Platformer.
