Nintendo has been having fun with the 20th anniversary of Pokémon. They have given away cards with a free level 100 Mew for the 3DS games. They have had the first Pokémon moviee on the official Pokémon site streaming. And now, during the recent Nintendo Pokémon Direct they have announced the next game in this massive series, Pokémon Moon and Pokémon Sun.
If this is not good enough for you, Nintendo is also releasing the original Pokémon games, Pokémon Red, Pokémon Blue, and Pokémon Yellow (Ok, that one is original-ish). These games are now available in the Nintendo eShop for the 3DS. A new feature in these digital versions will be access to the Pokémon Bank. These means you can go and catch the original 150, and then transfer them to Pokémon Sun or Pokémon Moon. Sounds like a completionist dream to me.
