The unexpected huge success of the Nintendo (NTDOY)(NTDOF) mobile game called Pokemon GO has huge ramifications for the industry. The game has quickly reached the top of the domestic iPhone charts grossing $1.6 million per day. Source: ThinkGamingThe biggest problem for other mobile-game developers is that Pokemon GO is taking market share from the other top games. As an example, Mobile Strike previously brought in $1.6 million per day suggesting up to a $400,000 drop in revenues due to the release of the Pokemon game. Even CSR Racing 2 from Zynga (ZNGA) has seen the daily revenue decline from $150,000 to $120,000. The Candy Crush franchise from King Digital now owned by Activision (ATVI) could take a hit if gamers shift spending to Nintendo games that are only now entering the market. For Nintendo, the company has a market cap in excess of $20 billion due to consoles requiring the company to maintain outsized revenues from mobile games to move the needle. As with any mobile game, the question remains whether the game has staying power. Games can quickly flame out so stay tuned. Disclosure: Long GLUU, ZNGA
