Various Dragon Ball smartphone games will become unavailable for purchase this month. In a message posted on the websites for Dragon Ball: Tap Battle, Dragon Ball RPG: Boyhood Arc, and Dragon Ball: Ultimate Swipe, Bandai Namco thanks people for playing and apologizes for the inconvenience. While the games themselves will be unavailable for purchase, any characters/stages/scenarios/etc. (various in-app purchases) will continue to work.

This announcement, strange as it is, comes right on the heels of the release for Dokkan Battle.

Thanks to @IMissBionix for the heads-up.
