Black and White follow the trends set up by previous games in the series. Two player characters (one male and one female) travel a new region, Unova, on their Pokémon journeys. This region is inhabited by various Pokémon, and unlike before, none of those available prior to Generation V can be obtained before defeating the Elite Four. The first of the new Pokémon to be featured in these games, Zorua and Zoroark, were revealed on February 10, 2010 in CoroCoro magazine, and the starter Pokémon were revealed in May.
The games' names were revealed on the official Japanese Pokémon website on April 9, and scans from the subsequent issue of the magazine were leaked on April 10. These scans revealed some of the graphical enhancements that are featured in these games. There is a higher level of 3D graphics than in previous games, as shown in some shots of the overworld. Initial sprites could be seen for Zorua, Zoroark, and the player characters.
In addition to the improved graphics, a number of aesthetic changes have been made from previous generations, including an altered battle scene containing fully animated Pokémon battle sprites as well as a dynamic camera that changes focus to highlight specific parts of the battle. Also, when talking to people, speech balloons for dialog will appear over people's heads, rather than as simply a dialog box.
