My Time at Sandrock is developer Pathea's second title, following up after My Time at Portia. Both games are life simulators in which you play as a builder who has come to the respective game's town to help restore it. But with both games being similar, you may be wondering if you need to play My Time at Portia before My Time at Sandrock.
The answer is no—you do not need to play My Time at Portia before playing My Time at Sandrock. Both titles are stand-alone and can be played without having knowledge of the other game. That being said, you will have a richer experience if you play the first game before My Time at Sandrock. My Time at Sandrock will make references to the first game you wouldn't understand without having played it.
