Nintendo is going mobile with free mobile games, but while players try to make it through the titles they will be objected to in-game purchases.

Nintendo will release their first mobile games soon and they will be known as "free-to-play," Polygon reports. However, according to information obtained from the Wall Street Journal, these games will rely heavily on in-game purchases to provide them with revenue.

Isao Moriyasu, president and CEO of DeNA, the mobile studio that is partnering with Nintendo to help create the smartphone games, confirmed that the five titles that will come out by Spring 2017 will all be free downloads. Moriyasu said that additional content inside the games can be purchased, but it is not required.

Nintendo's first mobile app is Miitomo and it was shown to investors at a meeting last month. Nintendo's president Tatsumi Kimishima said that the game would be a free download in March 2016. Moriyasu is avoiding calling Miitomo a game, considering it more of a communication app.

Fans were not all that excited when Miitomo was announced as the first title. They hoped that Nintendo would announce a better game, maybe something involving an original Nintendo character like Mario or Yoshi, and that it would come sooner, Slash Gear reports.

Nintendo and DeNA became partners in March and Nintendo's late president Satoru Iwata did not decline the free-to-play business idea. He actually was uncomfortable with the term "free to play" and preferred calling it "free to start."

Iwata said Nintendo did not want to damage its reputation and trust with consumers and entering into the mobile market would not lead to any lack of focus with its console business.

Future mobile games from Nintendo could be offered for a base price and not include the free-to-play model, but it will depend on the success of the first five titles.
