PC World description:
Pokémon Platinum is a new exciting adventure game for the Nintendo DS.
Team Galactic is up to its old tricks! This time they've set their sights on three Legendary titans of Sinnoh - Dialga, Palkia and Giratina and in this exciting new Pokémon adventure, you'll also encounter brand new characters together with new schemes and locations!
For example, Pokémon Platinum's network mode enables you to assemble up to 20 players from all over the world in the amusement park-style Wi-Fi Plaza where you can play games, take part in parades and even watch fireworks! You can also visit Distortion World, in which the normal rules of time, space and gravity don't apply, allowing you to walk sideways or even upside-down!
Take a trip to halt Team Galactic's sinister plot and come out a winner!
