Joke for Pokémon fans: Surely it should be called Platinum then? [Explaining / Ruining the joke: Pokémon games come in paired editions - red/blue, gold/silver, sword/shield. For the fourth generation of games the paired editions are Diamond/Pearl. In many generations an 'upper' edition is later released - Yellow, Crystal, Emerald - this is a slightly enhanced remake, often with a tweaked story. For the fourth generation the upper edition was called Platinum.]
