Nintendo shares jump 10% as Pokémon Go paints a hopeful picture of the future

Company appears to be relaxing its hold on franchises, potentially allowing new revenue to replace that lost by underwhelming console sales

Poki(C)mon GO is only out in a few countries so far, but the game's astonishing success is already having an impact far and wide.

A mobile game for iOS and Android, Poki(C)mon GO lets players catch the titular monsters in the "real" world. Players' physical locations are tracked, and when they are nearby a Poki(C)mon, they're free to catch it by playing a simple mini game. Points of interest become item-granting "Poki(C)stops" or player-battling gyms, while a pedometer feature lets players incubate and then hatch eggs, for yet more Poki(C)mon.
