Pokémon Pokopia’s original game file size was 6.2 GB.
The version-history information lists 6.2 GB for version 1.0.0, the game’s original release build. The same listed size also appears for the early 1.0.1 update, which fixed certain bugs shortly after launch.
A file size is different from the game’s sales figures. Pokémon Pokopia surpassed 2.2 million copies in its first four days, but 2.2 million is a sales number, not a storage requirement. That similarity makes the two figures particularly easy to confuse.
The size describes the digital data associated with the initial software version and can change as updates and downloadable content are installed. It should not be treated as the total space required for every later expansion or patch.
