You can play all alone, or, as is the crux of increased fun and true addiction, you can play Pokémon Go with friends, too. There's even a $35 wristband you can buy to accompany and enhance the game that's kinda like a Fitbit, but for Pokénerds, coming out later in July.
While Pokémon Go is free to download, in-game purchases allow you to "spend real money on PokéCoins," which "can then be exchanged for power-ups, extra items, and other enhancements." Now's a great time to cash in those Bitcoin for PokéCoins -- you'll be a regular Poké George Soros.
Nintendo and developer Niantic Labs haven't given a US release date yet for Pokémon GO, so you'll just have to stay tuned for that -- knowing full well whenever the game drops Stateside, you'll be able to point back to the day of your relapse.
