What qualifies as a "recreational building"?
I am trying to build a Great Hall in Oxygen Not Included and it requires a "recreational building". Forum posts said that a massage table counts, but I tried that and it did not work. The arcade takes a lot of research. Is there any easier option?
Expressive version.
Solution 1:
Build the Water Cooler, its the easiest to build and maintain recreational building.
From the Gamepedia page:
The Water Cooler serves as a "Recreational" object needed to create the Recreation Room as well as a gathering spot for Duplicants during break time.
