There's a brand new Pokémon game, and it's built entirely within 'Minecraft' — take a look

"Minecraft" is an incredible game. It's basically virtual Legos, and you can play it with dozens of friends. And sometimes, friends who play "Minecraft" together become people who create something magical in "Minecraft" together.

Such is the case with "Pokémon Cobalt and Amethyst," a "60- to 80-hour" Pokémon game built entirely within "Minecraft." For real! Just look at this:

We're talking about the good stuff: finding, battling, and capturing Pokémon — and then battling other Pokémon with the ones you've enslaved. There's a full story, various locales to explore, and much more. Better yet, it's entirely free! All you need is a copy of "Minecraft" on PC or Mac, and about 15 minutes.

Here's the deal:

The game is called "Pokémon Cobalt and Amethyst" — a nod to the naming convention of the Nintendo-made Pokémon games:

It's a full-on, brand-new "Pokémon" game — albeit one that isn't officially supported by The Pokémon Company or Nintendo.

The game took a remarkable 31 months to build; a small team of dedicated volunteers tackled the work. Rather than use existing Pokémon, there are 136 new ones created just for this game.
