Doctor Who: Worlds Apart

Doctor Who: Worlds Apart is a free-to-play digital collectible card game using a blockchain on a fork of Ethereum developed and published by Reality Gaming Group, based upon the BBC television series Doctor Who. The game has released for Microsoft Windows and macOS, and is planned to be released for mobile devices soon.

Gameplay
Players control a Time Lord, one of the races from the series, and need to challenge opponents with card decks which they build. The winning player is the one with the most Power. Each player has a customizable deck of 12 cards and 3 cards in your hand.

Card sets
Cards for the game operate on Reality Gaming Group's Digital Asset Trading (DAT) Platform. Each card is minted as an NFT on a "sidechain” and can be traded and sold on marketplaces. Prior to the game's release, cards were available to collect starting from October 2020.

Development
The game was first announced in August 2020 as a partnership between BBC Studios and Reality Gaming Group to create a digital trading card game based on the Doctor Who IP using blockchain technology. This would allow each collectible to be to be secured and protected by tokenizing as non-fungible tokens (NFTs).

Reality's co-founder Tony Pearce had said that understanding "what an NFT is” had proved difficult for Doctor Who fans at the start. Together with the BBC, they hoped to “educate the younger Doctor Who fans of why there is value and utility with these cards.”
