Pokémon cannot be stopped

The Pokémon franchise's never-ending quest to keep the 1990s alive continued today with the release of "Pokémon Black Version" and "Pokémon White Version" for the Nintendo DS.

The twin games boast 150-plus new Pokémon to catch and train. The in-game environments are timed to coincide with actual reality, so different Pokémon are said to be more difficult or easier to find during different seasons. Additional advertised features include broadband and infrared communications features for Pokémon battles and trades.
