The latest game from Katamari Damacy creator Keita Takahashi showed up during the September 2019 State of Play. A new trailer showed the Mayor communicating with other characters and interacting with them in fun ways. More importantly, it has a release window. In December 2019, people will be able to play it.
Wattam was first revealed at the 2014 PlayStation Experience. People play alone or together as they meet different anthropomorphic characters and enjoy their interactions.
Wattam will come to the PlayStation 4 in December 2019. It has not been confirmed if the PC version will arrive at the same time just yet.
