It’s official: Pokémon Brilliant Diamond & Shining Pearl are now released and available worldwide for the Nintendo Switch! These games are remakes of the original Pokémon Diamond & Pearl for the Nintendo DS, except with enhanced graphics, more modern gameplay, and more quality of life improvements.
The Marriland website is in the process of updating the Team Builder and Pokédex to add in support for Brilliant Diamond & Shining Pearl and these updates should be up fairly soon. Additionally, the Brilliant Diamond & Shining Pearl Walkthrough section of the website will begin soon as well to help get you through the game.
Look forward to these upcoming site updates and have fun with Brilliant Diamond and/or Shining Pearl!
