Pokemon Go: After Robberies ... Players Urged to Use Buddy System

Pokemon Go creators want players to catch 'em all, but to avoid getting jacked while you're doing it ... they're warning you not to play on your own.

Alleged robbers in Missouri used the GPS location features on the game to lure in unsuspecting gamers -- then pulled guns on them, according to cops. Four suspects were arrested.

The Pokemon Company International and Niantic, Inc tells TMZ it's aware of the incidents while playing the game, and encourage all people playing to "be aware of their surroundings and to play with friends when going to new or unfamiliar places."

For the uninitiated ... Pokemon Go is a mobile app that uses GPS location to encourage players to walk around their immediate surroundings and collect digital creatures.

BTW, in just a few days ... Pokemon Go has added over $7 billion in market value to Nintendo.
