Last year's freemium game Pokemon Rumble World is now available as a physical copy in North America, releasing with the maximum amount of premium currency.

As part of further celebrations for Pokemon's 20th anniversary in 2016, Nintendo has released Pokemon Rumble World as a physical game in North America.

Although initially a free-to-play title, the Pokemon title allows players to battle and collect over 700 varieties of toy Pokemon. The game also includes Mega Evolution, with Mega Rayquaza, Primal Kyogre and Primal Groudon being among the available transformations.

Since Rumble World's initial release last year as a freemium game on the Nintendo eShop, the game has slowly been making its way to retail stores, with physical copies becoming available around the world since November.

"We love giving our fans as many purchase options as possible," said Scott Moffitt, Nintendo of America’s Executive Vice President of Sales & Marketing. "Players that love collecting physical games and all things Pokemon will now be able to add Pokemon Rumble World to their Nintendo 3DS collection."

Although a physical release would suggest that the game would abandon its freemium model, Rumble World will actually still feature premium currency. To give players an incentive to pick up a physical copy over the free eShop version, Nintendo are shipping the game with 3000 PokeDiamonds, the maximum that players can hold at once.

Freemium players can gain up to 20 PokeDiamonds per day which gives physical copy holders quite the advantage, allowing them to progress significantly further in the game with fewer delays. The title hit shelves at the end of last week on April 29, and is priced at around $29.99.

In other Pokemon news, new details have been revealed for Pokemon GO, Nintendo's upcoming smart phone app. Shown through leaked footage of the game's beta, players will be able to customize their trainers before heading out into the world to catch Pokemon through Augmented Reality. This isn't the only way that the company is bringing the creatures into the real world if rumors can be believed about a live-action movie being in production.

Though Pokemon Rumble World is launching for 3DS, there's little doubt that fans are impatient for news of the upcoming main series titles Pokemon Sun and Moon. So far we know very little about the games, though the names of the two legendary creatures may have been revealed through Nintendo's early trademarks. Regardless, Rumble World along with the recent fighting game Pokken Tournament, might help to pass the time until the next big Pokemon release.
