The Nintendo stock has dropped by 11 percent following the launch of the mobile mario game Super Mario Run. The game has been downloaded over 37 million times in less than a week.

The drop in share price seems to be related to the user reviews that the game has received on Apple's App Store. In the first week of the game's release the game received over 50.000 user reviews with the current score averaging at 2.5 stars.

In some reviews players complain about the game's high price, stating that the content included in the game is not worth the €9.99 pricetag, while others state that the game is worth the price because it doesn't include microtransactions or ads.

Another reason for the stock drop may be related to the fact that Nintendo is not planning on releasing new content for the game, making investors wary of the game's revenue model.

Despite the drop, the company's share price has been steadily increasing since late 2012, meaning that the current 11 percent drop may be insignificant in the long run.

Super Mario Run launched last Thursday for iOS devices.
