The games that enslaved the world. The first Pokémon titles would be essential purchases if you could link them up to other Pokémon games available for the DS and, in the future, the 3DS, letting you shift Pokémon over to Diamond/Pearl, HeartGold/SoulSilver or Black/White. This wouldn’t be unlikely, as Nintendo have finally stopped their ‘We ain’t tampering with our old games’ business and letting you view GameBoy games in 3D. Also, let us link up with someone else who’s downloaded it. This would make for an essential purchase, more so than Gold/Silver, which is already playable in an enhanced form on the 3DS.
