Pokemon Brilliant Diamond and Shining Pearl is due for release at the end of this year according to an announcement from Nintendo at the Pokemon 25th Anniversary presentation. The newly reimagined version of the 2007 original will be released exclusively on the Nintendo Switch- but how much space will players need on their consoles?
The new game will be a polished remake of the 2007 original of Pokemon Diamond and Pearl games. This updated version will include the same story, well-known characters, and the same mechanics, but with far better graphics than before and a great new art style. Players will also notice how the game has been developed to stay true to its roots while looking thoroughly modern and aesthetically exciting.
According to the Nintendo eShop each game- Brillant Diamond and Shining Pearl- will be and estimated around 10G each, so about 20G if you want both at once.
If players take into consideration the fact that games do tend to update and increase in size, the games may come in nearer around 12 to 13G. Pokemon Sword/Shield was similar when it was released and then updated- it was released at almost 10G and then after a few updates it ended up requiring 12.4G of space.
