Fans are now excited for the upcoming augmented-reality version of animated game series, "Pokemon GO," for mobile phone devices. However, in spite of not having an exact date of its release, some said it is bigger compared to the "World of Warcraft."

"I think we can be bigger than World of Warcraft. There are more mobile devices than gaming-configured PCs out there," Niantic CEO John Hanke said in an interview with Venture Beat. "The awareness curve of what we're doing is maybe similar to free-to-play. I don't know if you can project your mind back a few years ago to when there was this thing going on in Korea - you don't buy the game, but you buy stuff in the game? It wasn't mainstream at all. It was this thing they did over in Asia."

"I'm not spending my time trying to beat everyone else out on paid user acquisition. We do these events because we're trying to build a genre from the ground up," the mobile game company chief marketing officer Mike Quigley added. "It takes a much more hand-crafted, thoughtful approach."

Meanwhile, developers didn't disclose the solid release date of "Pokemon GO," but there is a lot of surprises incorporated in the upcoming game. The mobile game is designed to be played on smartphones powered by iOS and Android, Moviepilot reported.

In fact, they created the series with real world surroundings so players can interact with virtual Pokemon. As a proof, they released a trailer, a few months ago, that showed how their supporters can enjoy the game.

Evidently, it brought a lot of excitement as it gave a nostalgic feeling for everyone who grew up in the evolution of Pokemon era. Also, it took them to their early childhood days, where they enjoyed playing the animated series. Watch the teaser below.
