Nintendo to release Super Mario Run in mobile game test

The game will start selling in 151 countries and regions later Thursday and will become available on Android-based devices at a later date.

The highly anticipated release comes after the Kyoto-based Wii console maker refused for years to move into smartphone gaming or license its characters for online play.

But, as it struggled to repair its finances, the firm changed course and announced last year it was teaming up with Japanese mobile specialist DeNA to develop games for smartphones and tablets based on its host of popular characters.

In March, Nintendo released its first mobile game "Miitomo" -- a free-to-play and interactive game that allows users to create avatars.

Then the Pokemon Go game -- based on Nintendo characters -- exploded into the public consciousness, being downloaded more than half a billion times.

But it was only partly Nintendo's creation -- the game is owned by San Francisco-based Niantic -- and it's had little impact on the firm's bottom line.

Super Mario Run, based on Nintendo's iconic Italian plumber, is the firm's most important move so far into mobile gaming.

Randy Nelson, head of mobile insights at US-based industry analyst group Sensor Tower, said it was likely to be a hit in the first month or so.

"We have no doubt that first month downloads of Super Mario Run will be historic -- likely much greater than Pokemon Go -- thanks to months of prominent featuring by Apple, extensive media coverage, and more," he wrote in a blog.

But a nearly $10 price tag to buy the full version could scare away some potential customers, Pokemon Go is free, and Android users won't be able to buy it until a later date.

"It's not like it will be Pokemon Go of 500 million downloads in two months," Macquarie Securities analyst David Gibson told Bloomberg News, instead estimating about 200 million downloads by the end of March.
